Style 2: Transfarring between PS3 and Vita for PS2 Remastered games. Listed as an example is the Metal Gear Solid HD Collection, which, this Style is the one that is the most confusing to everyone so far, since Konami's been fairly tight-lipped about it. Does this mean the Metal Gear Solid/Zone of the Enders (Possibly Silent Hill) Collections will also be available on the Vita? That.....seems like it would be the only case given the context of Transfarring (Swap your saves to play on the go and/or at home), but being able to play Zone of the Enders 2 -anywhere- is a dream I dare not dream lightly. So I'm going to wait for official word on that before I get my hopes up.
Style 3: Transfarring between PS3 and Vita for....PS3/Vita games. Listed here is the still-unannounced 'Fox Engine' game. This is the one that's pretty much what we've seen already with the title Ruin that claims you'll be able to stop playing the game on your PS3 or Vita (after saving), pick up whatever you weren't playing it on, and resuming from right (or about) where you left off. Which is fascinating technology, of course, if it works (which it didn't quite seem to do in the E3 Keynote, unfortunately. Maybe it was just all the nervousness though. The Ruin guys were just not prepared at all, poor dudes.) and I have no doubt that there will be -some- way to make it work.
Curiously, a lot of games weren't mentioned, but key of all is the already announced but on rocky waters Metal Gear Rising. Metal Gear Rising would certainly be considered an "Upcoming title" and, with the touchscreens on the Vita, it would seem a natural candidate for the precise cutting the game has been shown to offer. If the 360 version gets Kinect support (which, well, -was- announced, of course), it's possible the PS3 might get Move support as well and if all works out like it seems, then we just might get to cut watermelons on the go. (Also support structures and soldiers.) Perhaps that's even been what's holding the game up.
