In the past few weeks they haven't carried the following:
Tekken 3D Prime
All 5 of the PS Vita launch titles from Ubisoft
The Last Story Collector's Edition
The Last Story (mention seperately because they cancelled the CE then two days later the normal edition)
Mass Effect 3 (standard and collections edition, CE was GAME exclusive)
Mario Party 9
Now all future Nintendo and EA games aren't going to be available for the foreseeable future, probably more publishers will follow suit.
Basically it's all due to them loosing their credit insurance and publishers not wanting to take the risk/re-negotiate terms in time.
The day after they cancelled pre-orders for The Last Story CE an interview was conducted in which many things were said, including:
Can you guarantee pre-orders for games that you are currently selling?
Anna-Marie Mason: Absolutely.
