If this was Halo 5 we were talking about I'd agree that it would be a huge bundle, but MCC? At release a Halo:MCC bundle could have been a big deal, but MS squandered that opportunity. The game has already been on the market for 4 months, and most of a game's lifetime sales, even in a franchise with strong legs, happen in the first few months. The fact that the AC Unity bundle, which has been available for more than 4 months, is outselling the Halo:MCC bundle, speaks volumes.

Eh, I'm not really sure about that. Witcher 1 and 2 have sold well over 7 million copies combined, despite the first game being a PC exclusive and the 2nd game not releasing on a 2nd platform for a year. All signs suggest that Witcher 3 will be even more popular than Witcher 2, it's on 3 platforms at release, it's getting a much bigger marketing campaign (Xbox branded marketing since MS got the marketing deal), the fact that it's trailers are getting far more views, the fact that it has won over 100 awards before it has even released, including several fan voted most anticipated awards. I get the feeling it could top 8m lifetime across all 3 platforms, even more if it wins GOTY. I think Witcher 3 would make for a great bundle from May until September, when it could be replaced with a Halo 5 bundle possibly. Also, in August they could introduce a Madden + Joe Montana bundle in the US, get alot of football fans to choose Xbox One. In September they could do another FIFA bundle as well, assuming they got the FIFA marketing deal again this year, which would boost European sales if combined with a price drop.

Nobody have expected Killer Instinct at E3 2013 and Scalebound at E3 2014. Sry guys but you dont know what Microsoft Publishing Studio are cooking.
