Whenever I look at the background I always think back to Duo and his promise.
(If you didn't know, he is the final boss in EXE4 and came to destroy the evil that has collected on Earth. Rockman.EXE shows him the power of friendship through Lan and they end up beating Duo, but not defeating him. Duo tells them that he will come back through the galaxy and destroy Earth if necessary ((when evil comes back again))).
I think that it is a plausible theory of Du
S coming back, because it really feels like Capcom set him up to this. The main thing that is restraining this theory is that picture again. In the anime, Du
S just exploded the world, not just took it apart piece by piece. Granted that the anime and games have always been on different wave lengths (buh-duh-chk) I wouldn't mind beating the crap out of him again, though.
My theory on how Kizamaro will possibly get an FM: So everyone is fighting and he is like "D: I'm so useless" then a FM takes him over. >_> I really have no respect for that guy.
Fighting Rockman.EXE is kind of going against everything that Rockman was meant to be. Rockman is supposed to be a hero, not a "Look! There is some weird person over there that I haven't beaten up, so let's dismember him!" type of character. I would hardly even begin to think that Rockman.EXE would come back in form of a boss.
In any case, I would hardly believe the rumors. The only facts that we have are on the RnR3 page itself. If we actually believed all of the rumors then you could really Brother Band with Tsukasa in RnR1. Rumors=Rumors in the end.

Although I sincerely hope for some of these things to be real, just don't get your hopes up. If you do, they will be falling on top of you and crushing the last drops of life from your body.
