Joystiq has let the truth be told.

If you read about this over on Brendon’s blog, you were probably really excited at the prospect of a Nintendo DS version of Super Mario Galaxy. If you remain skeptical of any unofficial announcement - as I do - you would have spat at the idea instantly. This could have escalated into the Halo DS debacle all over again…all we needed was for Matt Casamassina to show up and start proclaiming that he has acquired a final build and it completely had sex with his eyeballs.
