I will be getting a PS4 Pro, likely at launch. Even though it upsets me that the Pro doesn't have a UHD Drive, I readily admit that I would likely only use it a handful of times due to my movie habits revolving around what my dad purchases on Vudu (to which I have access).
And while the Scorpio will undoubtedly have better visuals, those visuals may very well come too late. With no exclusives also a factor, I really see no reason to get a Scorpio.
Assuming the XB1S keeps its price in line with the cheapest 4K Bluray Player, I may grab one of those, but it's unlikely that will be the case. I'll probably grab a dedicated player around the $100-$150 range... Though I may end up skipping it entirely.
