I hadn't decided whether to pick this up or not and I think that I've just been pushed into making this a definite buy and now it's more a case of how long I can put off buying it so I don't get tempted to start before the X arrives (and knowing that last I checked, I have close to 300GB bandwidth left for October).
I put it off for literally minutes after this post, but, uh, it was done downloading before the end of the evening. Now I just have to convince myself not to start it up until I get my Scorpio on.
