[quote name='coopscohen']I went into BB yesterday and the in store kiosk had the 360 collectors edition for preorder.[/QUOTE]
If you print one and take it to the register, the system won't let you pre-order it. After the cashier scanned the barcode, there was a message on the screen saying that the item can't be added to the cart. At this point, I definitely wouldn't trust FYE or Target since they have been known to take orders for CE/LEs long after they are sold out and then not be able to fulfill them. TRU has come through for me in the past when doing a late preorder after the other major retailers have stopped taking orders.
It's hard to say if this will truly be limited or not. There's no doubt that demand for the 360 version will be strong during the release week, but this release will be diluted compared to the past two MEs since the PS3 version will be available at launch. I imagine that many 360 owners that really want the CE goodies but can't get the 360 version will either jump ship and play it on the PS3 (or PC) if they have both consoles, or they'll just buy the regular 360 version and pick up one of the other CEs for collecting purposes.
