Looking at past PSN releases, it is very uncommon for a release date of a PSN game to be announced more than 2 weeks in advance. Pixeljunk Eden had a one week lead time from announcement to download. The last Guy that was released last week had a 2 week hype period followed by a 1 week of demo before release. Elefunk went from unknown to available for download in about 48 hours.

I think if they are going to post on the PS blog about a release date, given the history it would be sooner instead of later. Let's hope they continue this trend eh?
