A Gamekult forum poster has published supposed details about Sony's E3 and beyond.
The poster is being seen as reliable by other sites, and has suggested that NGP's pricing and actual name will be announced in LA come June, with seven first party titles also due to be announced at the show.
The post also says that the NGP project Kojima first mentioned back in January is actually a port of Metal Gear Solid: Peace Walker.
Apparently there's another Metal Gear game coming in the future, although it isn't mentioned if it's for NGP or home consoles.
The poster is also claiming that Polyphony is working on something that will apparently release before March 2012, and that it intends to "make Europe a privilege for its next title," which could suggest a gamescom announce in Cologne in August.
It adds that Sony will announce games at E3 for release in 2012, that a sequel to Warhawk will be announced before the show, and The Last Guardian, Twisted Metal and Uncharted 3 will all be playable on the showfloor.
Apparently, 37 titles are in the works across multiple platforms, although most of them are not going to be announced until a European event, most likely gamescom.
We've asked Sony for comment.
