At least the weekly numbers appear to have stabilized allround for all platforms, that's the good news. The bad news is that the Wii U has stabilized at a very low average.
They'll be way off on their estimate, they'll hardly be able to ship any units at all in Q1 for 2013. I simply cannot imagine that Nintendo can be pleased with missing even this revised projection big time and ending up at around 60% of the original figure.
