Nope, my prediction is that the gap will actually remain pretty much as it is. Xb one Sept through Dec will sell as much as it did Jan-Aug. And Wii U should roughly double it's Jan-Aug sales. And those amount to similar holiday sales meaning the gap on 1 Jan will be about the same as it is now. Wii U approx 10 million, Xb one approx 8 million.
