Sega recently announced Sega Genesis Collection is now available in stores ... on the PS2. In the press release, Sega said the PSP version will ship later this month.
This really surprises me, because I've been expecting the two versions to ship simultaneously, and even IGN still has the PSP version with a Nov. 7 ship date. However, if we can believe Gamestop, they have the game set at a pre-release date of Nov. 16.
Sega gave no reason for the delay, but did mention the game will be rated "T" for Teen. I guess 15-year-old Genesis games can be too much for those 12-year-old kids out there.
