Who said it would? Kerotan? You could see that not happening almost a year ago.
Unless some pretty drastic pricecut comes, It will get very hard for sure. PS4 dropped quite a lot now compared to last year's numbers, where the PS4 was pulling over 15k per week even without releases, but now to reach 15k it needs already some fairly substantial game releases. At this rate the PS4 will just barely sell over 1M units for the whole year, a far cry from the 1.75M from last year.
