Well they did say that it was going to be rare!
Makes sense that it is sold out for all systems, as I assume it is generic bonuses with just the game for the system of choice inserted at the last minute. For all we know, these may be mostly PS3 or X360 orders...
Glad I ordered mine as well as I was on the fence to begin with. Glad that I didn't wait too long for content confirmation though! I hope that the contents of this CE don't vary from one another, as they did with the Sniper: Ghost Warrior CE
