The idea has potential and it would be awesome to see some marvel characters in smash. However if Nintendo wants to appeal to the West it needs new IP's. A racer for Europe and a FPS and a TPS for US. Next gen Nintendo has to get some third party support back and be the most powerful system in the market, with the most attractive hardware, gamers go to where the hardware is best for third party, (see PS4).
If Nintendo does the things listed above and makes a new (super)franchise possibly one featuring the avengers or something, it could become a relevant contender for MS and Sony in the console war, instead of a Switzerland which is doing his own thing and therefor sells not to well, except for the wii.
Please excuse my (probally) poor grammar
