If Wii sees shortages in January (sells ~ 1.4M), and Ps360 sees a slight growth over 08 January (X360 will at least), they can sell ~ 250K more that month.
Optimistically (for Ps360) the gap could now be 1M in total.
As we cannot expect Wii to outdo 2M/month, Ps360 would have to sell a measly 1M (or less) to not make it by March.
For the end of march (Q1) there's simply no hope (for Ps360).
So it is very likely that Wii will make it in February, but far from certain.
That is VGChartz LONGEST review. And it's NOT Cute Kitten DS
