Hello everyone!
First off, I'd liked to mention that I am excited for Mewtwo's return. I look forward to giving him a shot come April 15th as well as hopefully having an 8 Mewtwos match before the college semester ends. But Lucas's announcement sent me into a jubilee. I was only expecting details regarding Mewtwo, but once I saw Lucas's face, I jumped up and down in joy and my hands were shaking out of this confirmation. I have come to love Lucas very much recently and I look forward to making him one of my mains for Super Smash Bros. Wii U. The Smash Ballot I am also excited for because I look forward to see what will come out of it and I have a lot of say about my feelings towards potential DLC additions.
Currently I am expecting five to six characters to be DLC including Mewtwo and Lucas; at least three of them being veterans and two unique newcomers with room for one more veteran or newcomer (more likely the former). I am expecting Wolf to be announced at E3 as the DLC character. If two DLC characters gets announced at E3, my expectations will rise to six or seven characters, but I am not expecting that to happen. This means that competition for the remaining spots will be very intense and I'd advised everyone to keep expectations in check with regards to any newcomers (as well as any potential veterans beyond maybe Wolf). I'm not sure if we will get characters from the ballot for DLC, but I definitely think it will lead to consideration of the most wanted characters in the ballot.
Having said that, what do I feel could make up the remaining two to three spots? Inklings I feel are the most likely newcomers at this point. Splatoon looks like it could do very well critically and commercially and while I don't think they are in the works now, I do think that the likely critical praise Splatoon gets as well as the substantial increase in demand for Inklings will get them as DLC and if not, almost certainly in the default roster for Smash 6. They're the only newcomers I would be surprised to see excluded.
Roy is someone I feel who's chances are underestimated. He's a highly requested character who just happens to be an easy character to work with. I believe that veterans will be prioritized over newcomers (they take relatively little work in comparisons to newcomers) and after Wolf, I believe that Roy could very well be next in line should there be a fourth veteran. Being a highly popular character after all of these years and despite many people lambasting Roy for being a "Marth clone", "terrible in Fire Emblem 6", "not relevant" is not something to brush aside and even as a Marth clone, Roy would still be well received simply because of how fun he was to play with in Melee.
I don't think we will be seeing any new third-party characters. 99.99% of the remaining third-parties can't hope to match up to the likes of Snake, Sonic, Mega Man, and Pac-Man and I see no reason why Sakurai will make his stance on third-parties looser. Indies to me I feel are especially unlikely because of how obscure they are and none of them can be considered legendary and I feel companies like Nicalis, Inticreates, and especially Team Meat (who's suggestion, Super Meat Boy, doesn't even have a game on a Nintendo platform) don't understand how difficult it is to get third-parties into a Super Smash Bros. game. But I'll probably rant more about this later. Banjo-Kazooie would be an amazing addition to see, but I see no circumstances where a first-party Microsoft character would make it as DLC. The only new third-party I feel that could feasibly get in under Sakurai's strict criteria is Bomberman; but even then he's a dead franchise that would have to compete with Snake, so he's out as well. Snake is the only third-party that could plausibly return and even he has issues with returning as well. And it goes without saying, but characters like Ridley and Takamaru who are in roles beyond a trophy will almost certainly not be DLC although they may be in consideration for Smash 6 if they receive high enough votes or other circumstances changes (assuming that a Smash 6 does happen).
Still I feel as the pool of potential additions are larger than what we think, even in such intensely competitive environments. I feel characters like Isaac, Dixie Kong, Krystal, and Bandanna Dee are relatively plausible for potential characters as well as others not as frequently mentioned. Ice Climbers and Chorus Kids I also feel could very well be DLC as well, but I feel people will not like to hear the reason why this is a possibility.
As for who I voted, that went towards King K. Rool. I loved Rare SNES and N64 days and love the Donkey Kong franchise; DKC was one of my favorite games on the SNES (as well as one of the first video games I've ever beaten) and I also have very fond memories of the GBA DKC2 game as well as Donkey Kong 64. Next to Diddy Kong, King K. Rool is my favorite character from the franchise. I like his costume scheme he had in the Donkey Kong series and I enjoy his insanity and his relentless pursuit towards destroying the dang dirty Kongs over the course of at least nine Donkey Kong games. I don't know how much of a shot he has at getting in, but from what I've seen, it looks as he may be the most wanted character yet. My hope is that fan demand is high enough to where he'll be considered for DLC or if not, will be enough for him to return into the Donkey Kong franchise (the latter of which I am very optimistic about), but we will see.
Regardless of what happens, the DLC character scene is bound to be crazy. The funny part will be how wrong we are with the DLC choices.
