Has this really been confirmed? But what could have been the reason that they ended the Mega Man trailer with him fighting the Yellow Devil? I thought this hinted at single player content that was more strongly tied to the history of each character?
I'd rather have this by the way than another SSE. Just give me unique gameplay challenges that suit each character, so platforming for the Mario Bros., shooting and dodging bosses for Mega Man, fast running stages for Sonic, maybe flying for Pit, vertical climbing for the Ice Climbers, you get the idea.
By the way: has Sonic been confirmed as coming back or not? I would personally love it if both he, Mega Man and Pac-Man make an appearance to further complete the "classic game icon collection". (Though I've also always wanted to see Ryu in Smash for some reason, maybe just to see how he would handle outside of Capcom's games. Arthur from GnG might also be a good fit now that I think about it, or Haggar.)
