Most discussions I have seen on the 'web from people savvy to PSN pricing schemes and the whole "trophy" thing speculate that this will be a $40 USD release.

Key word here is "speculate" but that does seems about right to me. I'm sure Sony is right now running out the different price-point scenarios and guestimating what each would mean in terms of sales number vs. revenue per sale-- not to mention establishing a broader user base to whom Sony can potentially sell DLC-- and bragging rights in terms of online purchases for one of their long-held franchises.
