Batman: Arkham Asylum gamestop demo

I went to Gamestop today and they had a playable demo of Batman: AA. I asked the clerk if they were selling the demo, and he said it was already available for download on PSN. I checked PSN and couldn't find the demo. Does anyone else have this demo?

no

I haven't seen a demo yet for Batman.

I think it might be coming this week........
