They will probably release the Wario land games in order so I doubt that Wario land 3 will be a launch titile. Also I doubt that they will release any mega man xtreme games before they've released all the mega man classic GB games.

I just thought it'd be a good idea to get the Wario series underway. Also, the Game Boy Color needs a Mega Man game as well.

Although, they could have the option of switching to SGB mode.
