At this point, we should expect UC4 to outsell H5, just based upon the sales of UC3 (~6.7M) and H4 (9.5M), on the respective install bases (launch year totals of ~61M vs. ~74M, respectively). Those number represent attach rates of 11% and 13%, respectively. Right now, PS4 has effectively outsold the X1 at a 2:1 margin, which is far more significant than the total volume differential (if we're matching them against LTD console sales and not launch years). UC4 just has a much smaller hill to climb this generation, and any other advantages that it may get will make the climb that much easier.
