At E3, Sony said that a ton of PSOne games were coming to the PlayStation Store. Today the ESRB revealed one big addition.

They've rated Metal Gear Solid for the PSP and PS3. In other words, look for the game to hit PlayStation Network soon. Unfortunately, the ESRB doesn't reveal a release date so it's up to Sony to announce that.

Rumors of MGS's re-release have been swirling for >a couple weeks now. Yesterday, the PlayStation Store received Final Fantasy 7 so it's been a pretty good week for retro PlayStation gamers.

Update: Originally we stated that RE: Director's Cut and Rainbow Six were rated. Both games have hit PS Store in the last two weeks already, though. Our bad.
