The XBox version of the game may or may not be region specific. I assume that choice is up to the publisher, so we will not know until after the English publisher(s) have been announced.

The PC version should not have any region restrictions, which is presumably what LightningLockey was referring to, since that version is what the original poster specified. I've ordered a number of PC games from the UK, and prefer their DVD style case to North American's half empty boxes or double wide DVD cases wrapped in a cardboard sleeve. Also, ordering older games off eBay, etc, I've generally found the shipping comparable or cheaper than from the US, and the shipping times faster.
