Nice..
More welcome additions. I don't have any DTS:MA 7.1 discs yet (and only one DTS:MA 5.1 - DieHard 4.0), but will keep any eye out.
The store revemp, which is no longer a web based store, it's now build into the PS3, as a XMB application, is very slick (looks like they borrowed lots of Singstore code..), and works very quickly. The icons take a while to appear, but it does seem as thou they get cached locally, as next time, they appear instantly.
Pretty much the only thing missing right now, is in-game/cross game messaging and invites. Once that's done, it has everything the 360 has, and more.
