Mostly PS3 stuff, but not their Vita equivalents, alas. However, there is Everybody's Tennis for PSP and Vita, which is down to an unmissable £3.19, and the promise of some some more PS1 and PSP titles in the mix. A shame that Everybody's Golf Vita doesn't get a chip, given the incoming update.
Find out more on the EU PSN blog. The sale starts tomorrow along with the EU update. I'll update if anything interesting is added to the list.
