I caved and ordered the 74.99 one a few days ago when this was first posted. Thanks OP!
However, I'm here to report that it arrived today and that I didn't receive the codes either. I got the Kinect and Kinect Adventures... I also complained because my reciept lists that it also included Gunstringer, and there was no mention of Fruit Ninja either, but I'm assuming you get both as per what was posted here.
The only options they offered me is returning it for a refund in full, or a refund of 20% if I keep it. I'm alright with the 20% refund... I just explained that it DID state I would receive Gunstringer as well. Hoping for the best, but I'll take what I can get. This one was a mistake, but for the price, I won't complain too much. They did good by me in my opinion. I hope anyone else who ordered gets them though.
