I'm going to go out on a limb and say that PS4 at 23 > Xb one at 28 +39 on the monthly chart. Which means PS4 should squeak in a win for NPD. But that's about 70/30 still so not totally confident. My prediction was that Xb one could win both April and May but it looks slightly more likely that it won't win both months.
