No, that is very far from safe. Consider:
-The PS4 remains ahead in the US overall by a decent margin
-You are relying on two weeks of sketchy VGC tracking
-The Xbone is selling bundles for $350 with much heavier marketing, while Sony are selling basic PS4 packages for $400 with less advertising
-The PS4 has a strong games advantage
-VGC's numbers are quite close here, so it's not the kind of weekly gap which produces confident projections
-If you put any stock in Amazon analysis, we've seen the Xbone totally lose its lead on there since the holiday parental buying spree. All other major retailets indicate the same thing.
Another note: Even if your general premise turned out to be correct, that would not be "winning back" NA. MS have only won back the NA market when their matketshare vs. PS4 is as good or better than 360 vs. PS3. Unless they accomplish that (incredibly unlikely), they have still lost something they once had.
