Will GAME sell through their launch day allocation of the Wii U ahead of release day? The answer is "Yes". 

This comes from a spokesperson for the retailer who spoke recently to Videogamer.com. It seems that the Black Wii U Premium Console SKU and Black Wii U Premium Console with ZombiU SKU will almost certainly sell through on launch day. 

But what about the white Wii U Basic Console? It seems they may have already sold through their launch day allocation as it's no longer available on the GAME website. 

"Nintendo have advised, 'Wii U stock levels will be tight on day one, however we will be providing retailers with regular stock deliveries in the run up to Christmas in order to meet demand as quickly as possible.'"

Don't fear though, GAME stated that they're "very" confident that those who have already pre-ordered a console will receive one on launch day.
