Sony's fault or the studios?
Clearly James would like to blame Sony for this, but the reality is clear for all but the idiots to see.
Sony have managed to get all 8 of the big movie studios onboard for the US launch, and that came at a price, they had to region lock content, and only allow other region access, when allowed to do so by the copyright holder.
Clearly Sony are not to blame for this, it's the studios wanting to keep their regional locks on content. It's worth pointing out that all Sony PS3 and PSP games have no region lock, which is a clear indicator is to what Sony think about regional locking.
