The ESRB has rated both Grand Theft Auto III and Grand Theft Auto: Vice City for PS3 releases. Sony Computer Entertainment America is noted as the publisher, since these games are slated to arrive on the PSN as "PS2 Classics."
We had recently learned that the original Killzone was coming to the PlayStation Network, and this new information indicates that Sony's stepped up its efforts in getting PS2 games in a digital format. Hopefully we'll get some real classics, like the Altered Beast remake, or Shadow the Hedgehog. You know what I'm talkin' about.
In all seriousness, this is cool by me. I quite fancy playing Vice City again.
