Wipeout 2048 and Gravity Rush if it's a launch title. Otherwise I'll probably just wait for it. One of the smaller PSN releases seems like a very likely purchase though. I really like how Escape Plan looks.
Other than that I'm not really in any rush considering February will be an exceptionally busy (and expensive) gaming month for me, even without the Vita. (FFXIII-2, RE Revelations, possibly Kingdoms of Amalur)
I heard that retail outlets didn't want too many games at launch day, for the Vita.
And they tought it were better to space out some releases, at first I laughed when I read it.
But when I saw a title like Unit 13 (a SCEA-developed title) is available at launch-day in Europe, while it's in the launch window in US, I figured it might be too much with 10+ launch-titles from Sony the publisher, if they also wanted to get room for third-party stuff aswell. :-/
Gravity Rush, and Escape Plan will launch as PSN exclusives, don't know if they come to retail later.
I think that's some strange choices, clearly those games are in higher demand from potential day one adopters than some of the other titles.
Shuhei Yoshida even said he agreed on Twitter (@yosp) that it (Grabvity Daze) should be in retail, but it were SCEE's decision, not his.
Escape-plan is launch-title in both territories.
But Gravity Rush were listed as a launch-window (not launch-day) game in US, so I guess it's perhaps, around early march. :-/
In the SCEE-blog, it were not clear when they announced the launch titles if Gravity Rush would come out at launch, they said they had more information on pricing and dates on the PSN only games, closer to the system's launch.
Since users can switch on/off Vita or swipe to other apps in the middle of a game (or after a race), the load time should not affect us too much.
I don't think the games will continue to load in the background if you multi-task while loading, when you initiate the, multitasking it freeze your game, create a solid-state save and place a thumnail for the game in it's Live-Area, pretty much instantaneously.
So when you get back to the area, and click the thumbnail, I think it will continue to load.
I only tought that Gameloft/Ubisoft-Hack'n slash RPG had really bad loading, likeit were running of a UMD or something.
All the other gameplay I had seen were pretty fast.
Havn't checked out Wipeout-loading yet tough.
I planned not to buy it, because it's allways gotten too hard for me, to quickly.
But I hear they've tried to make this more acceessible, and give you more different strategic choices with regards to your veihicle.
