wow

does any1 know if this game is free roam at all.

personally i think that is something that could work pretty radically. like imagine jumping off those buildings and then sailing on down.

By the sound of what they've released already, it'll be more dark and claustrophobic like Bioshock, not a free roamer.

Apparently the game is set for a June 9th, 2009 release...sooner than expected, awesome!

I don't think there's a confirmed release date for Europe yet, different sites state that it's either:

29th May
9th June
12th June

Is the release date you said for everywhere or just America?

Amazon.co.uk (haven't checked Amazon.com yet) have next to the listing 'will be released June 19'.

So either Amazon is selling it early (which is more than likely) or the June 23rd date is set for UK too.

EDIT: Amazon.com have the listing as June 9th. Curiouser and curiouser...
