I'm with Evan_B a bit in that having got Smash 3DS and replaying Melee a bit before its release, I'm feeling content Smash-wise so getting more info on another Smash game hasn't got me excited even if I know the Wii U version is the more superior product. It could be that this direct gets me pumped back up again for its release but right now I'm indifferent to the news and would be more interested in what future products may be coming out next year for the 3DS and Wii U.
Specifically, if there will be more exclusive software for the New 3DS or how that may affect its line-up. Aside from Pokémon coming out next month, the 3DS just seems to have a lot of smaller releases coming out but nothing major. Clearly, Nintendo wants to extend the life of the 3DS so what software will the provide to do so.
