I have this on preorder from GAME as soon as it was available for preorder.
btw, as it seems, this will be a GAME/gamestation exclusive in the UK.
I contacted shopto.net about getting this item, they said something in the line of: "we will not be able to have this item in stock".
also, if you go on masseffect.bioware.com and change the country (upper right corner) to the UK, only Origin (for digital copy) and GAME show up. No amazon, best buy, HMV, etc.
