It's natural for gamers to speculate and start spouting off rumors as we get closer to E3, but the rumor mill is really working overtime today. A man named John Gilbert has recently posted a story about upcoming NGP/PS Vita launch titles. Unfortunately he didn't cite a source, so take this all with a grain of salt.
The list begins with three titles we have seen mentioned for the NGP in the past: Uncharted, Call of Duty, and Little Deviants. We actually know for certain that Little Deviants—basically a demo showing off the NGP's rear touch panel—and Uncharted will both be coming out in the future, since we've seen playable demos for both. And honestly, if Call of Duty doesn't come out for the portable as well, I'll eat my hat.
The list goes on to mention Lumines, Sonic Generations, Mortal Kombat, Lego Harry Potter, Pro Evolution Soccer, Super Street Fighter IV: Arcade Edition, F1 2011, Hot Shots Golf Next, FIFA 12, and Wipeout. There isn't a whole lot of info about these games, although it's peculiar that most of them are ports. Then again, games like Super Street Fighter IV: Arcade Edition have been used in examples when talking about the NGP's capabilities in the past, so it's not that hard to believe that they would see a NGP release. Still, this is all rumor and speculation, but juicy rumor and speculation nonetheless.
