Sadly, there seem to be no new releases this week. There will be a few later in the month, but for now, take this opportunity to catch up on older games (surely you haven't played them all, have you?).

Release dates are collected from a number of sources, so there will occasionally be errors. Please note that some games may be released in some parts of the world and not others.

Don't get too excited about seeing Gravity Rush on the list below. The PlayStation website says May 1st in one place, and June 12th in another--and June 12th seems to be the most likely.

Like the PSP, the PS Vita has a built-in web browser. The good news is, the PS Vita's browser is a lot better than the PSP's (and easier to navigate due to its touch controls). The not-so-good news is, it's still not as intuitive as a PC web browser.

It is fairly simple to get the hang of, once you know what all the icons mean and what you can and can't do with it.
