I tried to find the PS3 chat topic but failed to so.....anyways
According to IGN on Aprial 17 (im pretty sure) the PSN store is going to get a new look that will help users navigate the store more easily and such, plus the new interface looks pretty fuckin cool too.
(I would post a link but well, fuck school web restrictions)

As such, there wont be any new material on the store until the update comes out. Check IGN for more details as well as post a link for me because i lack the ability to do so...

Seems pretty cool, you got any pics of the store ??

I was gonna post them but i do the majority of my posting in school which is where i am right now and IGN is blocked
