The PSN account requirement makes little sense to me. If they made it optional, almost every PlayStation owner would probably use it anyway, leaving the non-PS owners the interesting case. By forcing non-PS owners to use a PSN account, I don't believe Sony has much to gain, since what benefit could Sony possibly get from requiring an account? It's not like Sony has much to sell to non-PS owners, and forcing them to use an account isn't going to make them much more likely to get a PlayStation either. On the other hand, there's going to be a good number of people that aren't getting games they might otherwise be getting. My guess is that this is at best a very minor win to Sony, but the badwill gained from this nonsense shouldn't be worth it.
The PvP demos were mentioned. I don't really care much for PvP, but I did download the Delta Force demo because I'm interested in the game despite the PvP factor. I haven't tried it yet though, but I should have time this weekend (well I'd better have, because I think the demo won't be available much longer).
