The Wii U is currently on a path of recover, which is mostly in-part due to the September 20th price drop that happened earlier this Fall. Nintendo has miraculously managed to actually get the system moving in Europe and even Japan, which prior to this season was an extremely difficult task for the company.
But it’s going to take more than one successful holiday season to consider the system officially in the clear. As we saw with the first 45 days of the Wii U’s life, the system sold extremely well. But once 2013 rolled around, it sunk faster than Rosie O’Donnel in a swimming pool. So no system is ever automatically set to succeed all because it has isolated moments of glory.
