Going with a PS4 lead, but only small. Won't be >200k like last year, probably <100k.
Interesting, what's your reasoning there? I know everything we've seen so far are just estimates, but they're the only evidence we have. And they seem to indicate a bigger win.
The InfoScout report implies a 25% advantage to PS4 on Black Friday (based on a 5:1 retail

nline split). I'm not sure what proportion of November sales are on Black Friday, but I'd bet it's at least a third. If Xbox One sells 1m for the month--a very conservative estimate, strongly down YOY--then PS4 would have a 75,000 unit advantage from Black Friday alone.
Adobe's estimate was that the rest of the month also had a PS4 advantage (of unknown size) in online sales. With no evidence that relative retail/online positions were flipped, that seems to add somewhere between "more" and "lots more" to the PS4 win gap.
Staying under 100,000 seems pretty unlikely if those circumstances obtain. So what part(s) of it seem least plausible to you?
