If Amazon remains accurate, X1 may be in for a tough month. Even the regular Star Wars bundle has been comfortably ahead of the Fallout bundle, which I assume MS deem their biggest sku for the majority of the month before BF. Star Wars LE bundle preorders seem well ahead of the Halo bundle, and Cod may get close to Halo numbers as well, although I think it will be a bit short.
Does anyone remember last November when MS announced/released all those bundles and X1 was outselling PS4 4/5:1? Nothing they have this year comes close to the value of the Ass Creed bundle.
