They havent said which stores will carry that preorder bonus though. It could be all of them as long as you preorder. Which means if the game comes out on steam then that works fine for me.
The preorder exclusives are region specific. That link earlier with the machine gun and flechette rounds, those exclusives are only available to European gamers.
The US exclusives haven't been revealed yet, but unless I'm misunderstanding or something changes if you buy this in the US you'll never get that machine gun or those dumb shotgun shells.
fix;di don think i ever ben as exited as i am as for this new game i am i am
seriously doubt they would lock it out via region.
Claim battlefield superiority this Autumn! The Battlefield 3 Limited Edition: Physical Warfare Pack is now available for pre-order exclusively at GAME and Gamestation in the UK.
You can take that to mean those two retailers are the UK exclusive, but I don't think so. From the comments on the page and the way it's worded, I think that pack is a UK exclusive.
