First off i dont remember talking to any of you guys and have no idea where you got the info you posted :)
Officially:
-Super Meat Boy will come out on Wiiware and PC before 2010
-The PC release will initially be digital, but i will be releasing a special indie edition in the same way i released my TIACFH cd.
-We might do a retail release for PC/Mac after its Wiiware release, but thats not set in stone.
-SMB will feature a VS mode where the players can interact, and the person in the lead will control the scroll of the level.
-SMB will feature 100+ levels not featured in the flash version.
-None of the art/programming/endings of the flash version will be featured in the Wiiware version, SMB will be remade from the ground up with all the bells and whistles you would expect from any "good" wiiware title.
-SMB will feature boss fights
-We hope to release a level editor, for the wii version but again thats not set in stone.
tell me if you have any more questions
