It depends which version MS is going to promote heavily. If it's going to be $399 no kinect vs $449 kinect plus a game, as it was with the Titanfall bundles, yeah you could be right.
If by the end of the year the version without Kinect is getting good bundles, and the difference is $100 again then no way. And the WiiU sales will pick up holiday season as well with a price cut and some good bundles. $239 currently for the Skylanders swap force bundle.
