Yesterday as part of the PlayStation Store update the demo for Uncharted: Drake's Fortune was released on the American PlayStation Store. The Australian PlayStation Store was updated but a demo for Drake's Fortune was conspicuously missing.
Australians missing out on demos isn't a new thing, so a lot of people have created an American PlayStation Store account to download these demos. Those who did so today got a bit of a shock, with the demo coming up with a message to insert a disk to proceed.
Kotaku contacted Sony Computer Entertainment America about the locking and they confirmed that the US demo "does not allow for cross-region play". According to Kotaku the Sony spokesperson stated "the Japanese and PAL demo will both be released soon, but we don't have confirmed release dates".
