According to the front page of the official
Folklore game site, the demo should be hitting the PSN for us in that place just above South America tomorrow some time. No word on whether it's the same limited-time demo that Europeans just got their hands on, but I'd be willing to bet that it does, indeed, hold the same restriction. So hold tight to your demo while you have it, because you'll only have it for 8 days. Also: Sony servers should be down tomorrow night in an attempt to be as cool as Bioshock. Just like Johnny Knoxville wanted to be as cool as Tom Green.
On a completely related side-note: I'm here to remind you that Sony's
Folklore Create-A-Creature Contest is still running until the 31st of this month. You can spot my submission below. Send good word to Sony for Beasttoid.
EDIT: Okay, so apparently the download is staying available for only 8 days, but the demo stays on your harddrive forever.
