Another big Vita week for the PSN update. Last week's "early" launch saw the additions of Escape Plan, Hustle Kings, and Super Stardust Delta -- that last one being the free 3G game. This week we see the addition of Touch My Katamari, perrenial favorite Plants vs. Zombies and several augmented reality. Of course, for further pertinent PS Vita information, head on over to our Joystiq Vita launch guide. PSN Plus subscribers can pick up six classic Sega titles for free this week, which includes the first two Sonic the Hedgehog titles, Golden Axe (call dibs on dwarf!) and Altered Beast. Also, don't forget to check out the demos for SSX and Shank 2. Check out the full list of this week's content over on the PlayStation Blog.
