Of course, that's why the Wii U has been outselling both, since it is HW B/C, which is the best. And the XBO started outselling the PS4 WW since the announcement of B/C. Oh wait...
I was living in an alternate world where B/C is more than a nice feature that in the end means jack shit.
What does this have to show? No one expected the XB1 and Wii U to start outselling the PS4. What this is is simply a way to get Xbox 360 user's to upgrade. Everyone knows the PS4 has won the generation, don't need to keep rubbing it in.
The point is people keep making it out like B/C is a huge deal, especially after XBO announced theirs. Some saying it won XBO E3 since it was so big. However, sales, even after the announcement, prove that the vast majority of people don't give a shit about it. It's a nice feature to have, but doesn't make the slightest difference, so there's little reason to continually bring it up like it'll mean anything.
