Well, before anything gets done homebrew-wise, tool-chains will have to be made (or the Sony SDK will have to be used, but no one legit will want to touch that) and that is going to take time and effort. Projects like this by devs like this are going to help split the PS3 wide open in the long run.
Personally, I'm hoping for another Nethack clone like I have on my CFW PSP (that I've put more time than I'm willing to admit), but maybe that's just me. ;)
