Currently, it looks like X1 will win Amazon sales for December (barring a massive PS4 surge), as the monthly gap is quite significant. As far as being an indicator of NPD for December, Amazon loses some of it's value as an indicator for overall sales. Some have mentioned previously that the effect of sales at multiple other outlets is not negligible, and I concur. In addition to that, December is usually (and appears to be again) a supply-constrained month that is featuring uneven console distribution to retailers (Wouldn't you, if GS and BB made up a much larger segment of the market?). What unnerves me about using the other retailers' online statistics is that they don't appear to be nearly as clear cut as Amazon.
