This falls into the same problem Nintendo has. They are dependent on their consoles to make or break the companies at this point.
Sony will be OK, as the PS4 will be very successful this next 12-18 months for sure.
The difference being that Sony had to sell their two largest office buildings for about $2 Billion so that they could afford to launch the PS4 and Nintendo is sitting on about $14 Billion in cash. If the PS4 does as well as the PS3 and the Wii U only does as well as the Gamecube, unless something big was to happen, Nintendo would still be sitting in a much healthier financial position. If the Wii U stopped selling today and Nintendo re-structured, they would still be better off than Sony is.

Net assets is counting up the value of everything Nintendo owns, including cash, thigns that can be easily and quickly turned into cash (inventory), and things that can only very slowly/with difficulty be turned into cash (buildings, brand name etc), minus everything they owe (taxes, debt, .
