While everyone's busy looking into Metal Gear Solid: Rising and what systems it might or might not be on, Konami has smuggled another title into E3; Lords of Shadow. If GamesPress is to be believed, this title has now become a Castlevania sequel.
The site also mentions Metal Gear Solid: Peace Walker, a PSP title. This reveal is in line with John Koller's announcement in this weekend's QORE that a new Metal Gear Solid will be coming to the PSP Go.
