He said way back in 2006 (I think in October) that he'd release the game within a 16 week window. Then he extended it 9 weeks. Regardless, it's been way more than that, so I guess he's just disappeared again. Even before that he said he'd post the finished game on his MySpace, which has been around forever now. So I guess I wouldn't take anything he says seriously until he actually releases a demo or something.
For those that don't know, "Demo 4" is the infamous demo that was supposed to include material all the way up until pulling the master sword out.
