Wired: People who own older versions of Sony's PSP have been playing Dissidia: Final Fantasy for months.
I for one didn't like Dissidia very much, so maybe it's their loss. But early adopters who grabbed the PSP Go when it came out on October 1 have had to wait until Thursday to nab the Square Enix fighting game, which can be downloaded via the PlayStation Network for $40.
Good, but not fast enough.
