They've been saying that the original incarnation of Mega Man would be retired since way back when Mega Man Legends first came out... I wouldn't mind if future games starring the original stuck to the handhelds, if only to keep the character going. Speaking of which, I want another Legends game, if only for Tron Bonne.
One of the arcade games must be Mega Man Power Battles, which is primarily a series of boss battles in a row, but I can't guess at the other one. Wasn't there a kart racing-type Mega Man game?
