Sorry if this has been answered but will there be a demo on the PSN and if so when will it be released??

Its been mentioned that there will be one 2 to 3 weeks before release.

Im hoping for one in 2 weeks

Demo's are generally released 2-3 weeks before the game is released to generate more hype. Releasing a demo over a month or two months is counter-productive because the hype by the rest of the media/internet would be lost and have gone stale. There needs to be a general progression.

Unfortunately, I'd love to see one immediately but we probably won't get one until the first week of June or very very late May.
