Doritos Dash of Destruction has been released on the XBLA as a free download. I figured I'd mention this now since I don't know how long it will remain free for.
I got it - haven't tried it yet but the early reviews say that for free, it's not bad. Apparently, there's a free Toyota Yaris-themed game (called "Yaris") that was (is?) available on XBLA, but it's supposedly ridiculously bad, whereas the Doritos game is on par with a decent browser game.
In other news, Bomberman Live is currently on sale for 600 points (down from 800), and they've unlocked the Time Trial option in the Mirror's Edge demo.

I wait to do these until the PSN Store updates, because that's usually more interesting than the store releases. Even more so when there's no releases. There just hasn't been a PSN Store update this week either.
