When all is said and done, I wonder if we'll see a Smash Bros Complete edition next year with all the DLC released after they finish all the DLC they want to make?
I think we might. It would also make for an interesting launch title for a new system, maybe even adding exclusive NX characters like Ice Climbers or something else that requires more power. A person getting the collection will be in for a treat too, with a roster that'll probably be close to 60 strong. Who know, maybe at the end of all this the only cut character not in Smash 4 will be Snake and Young Link, the latter because he's pointless with Toon Link and the former because of Konami. Really, it's entirely realistic, especially since the remaining Melee cuts are two easy clones. That's a lot of Pokemon DLC though haha
I think at the end of Smash 4's life, it'll end up being more like Smash 4.5 and the line between 4 and 5 might be kind of blurry. Smash 5 might end up just being a ported complete collection for Smash 4 with a handful of new characters, rather than the tradition massive release.
