The Xbone bundle will mean nothing if Sony offers a free game with the console for that week. Microsoft opened the flood gates with that type of behavior. Sony then used it for FIFA when they didn't have the "Official" bundle and it worked wonders. If you were able to get the superior version of CoD and a PS4 for 399, why would anyone buy an overpriced Xbone for 499.99..

I think the PS4 version gets boost ( as X1 also will ).
With the larger player base on PS4 giving this win to the PS4.

I just realized the COD XB1 bundles is with a 1TB XB1 and is $499.

Do you think it was the best choice to make this a higher price model? The AC:U bundle is $399.

In the US maybe, but worldwide no.

In the US, XB1 outsold by 1.40 to 1.45.  This was launching when the two systems had similar user bases though, so now it's less certain I'd say.

Worldwide The PS4 outsold XB1 by 2.71 to 2.06, and will likely handily outsell again.
