Oh man, I just realised; major buzzkill for me.
These are going to be locked to Region A, aren't they? Do any of the current Sony Godzilla Blu-rays play on non-American players? Looking on Bluray.com it looks like none of them do, and if G2K turns out to be region-locked as well then I'll probably have to continue waiting indefinitely for a version that features the original Japanese cut and English subs that I can actually watch.
