Last Year Feb for PS4 was 285k and last march was 371k. March is a bigger month than Feb.
Paradoxically, February is most frequently the bigger month despite March having five weeks. Out of 53 individual Q1s in the U.S. for every major system released in the past 20 years that I have data for (except the Saturn as my fifth-gen monthly data is only in graph form along with the PS1 & N64 and it doesn't really show up because it sold that poorly), only 15 had March up from February. Two of those were of course the PS4 & XBO from last year, but it's worth pointing out that last March had Titanfall and Infamous as notable exclusives. So, statistically speaking the PS4 and XBO are likely to decline this month from February, if not by much. Depends on what effects software has on sales. The PS4 has Bloodborne, MLB 15 and FF Type-0 HD and both systems have Battlefield: Hardline, though whether these games move any significant amounts of hardware remains to be seen
