Well, the Q&A has been released in English, and as expected the reality isn't as simple as the Wii U is now profitable.
The quote was
"With respect to the impact of Wii U hardware sales on profit and loss, in order to sell 3.60 million units, we have to produce some more hardware units on top of our current hardware inventory. However, since the loss arising due to the hardware production costs being higher than our trade price was taken into account in the previous fiscal year, you could assume that there will be almost no loss this fiscal year for the sales of the 3.60 million hardware units."
It seems that a devaluation of their current inventory of Wii U's occured in the previous fiscal year. So they are still being sold at a loss, it's just that accounting wise, the loss was booked in the previous fiscal year. Also, "almost no loss" is still a loss. So even with the devaluation of their inventory and their projections for the costs of Wii U's still to be manufactured, they aren't projecting profitability for the Wii U hardware over this fiscal year.
There are also other factors that I have discussed in my previous posts. For example, the Mario Kart bundle will likely comprise a significant portion of hardware sales and it is being sold at a higher price than the previously available bundles.
