At this point I'm expecting Smash 4 to be Brawl 2 without:
-tripping
-a single character that completely breaks the game
anything more than that is a bonus. I don't expect Sakurai, Iwata or Nintendo to "learn" fuck all from Evo, competitive Smash, or anything that exists outside of their pathetic bubble. Luckily, Melee isn't going anywhere.
Biggest disappointments of the gen:
1. Brawl (Dojo hype is what really did it. No game had hype like that going into it. Not to mention it was the sequel to fucking Super Smash Bros Melee. Expectations we going to be extremely high no matter what, but the Dojo put them into overdrive. Then the game sucked ass.)
2. Twilight Princess (Wii hype helped with this one. E3 2004 trailer was, and still is the greatest video game trailer of all time. People were waiting for a realistic Zelda on the Gamecube since that Spaceworld tech demo in 2000. Then the game came out and it was ass compared to Wind Waker, let alone MM and OOT)
3. RE5 (Coming off of RE4, this was a huge disappointment. That was when I realized the name of the game doesn't mean shit if the people behind the great games, namely Mikami, aren't involved. RE5 ->RE6 was fucking horrible too, but my expectations were much lower since RE5 sucked and every RE6 trailer looked horrible too.)
4. GTA IV (Remember how fun VC and SA were? LETS TAKE ALL OF THAT FUN AWAY. you get GTA IV! What a piece of boring shit. Thank god GTA V completely obliterated that game in every possible way.)
5. Skyward Sword ("surely it couldn't be worse than Twilight Princess!" It was worse than Twilight Princess)
