Remember finding out about the N capable WNA for the 360, and then wanting one? Well, today was supposedly the release day (I had it pegged as next Tuesday in my calendar), and it's gone missing from virtually every online shopping area. The only place Google Shopping turns up is Buy.com with a "sold out" sticker on the page.
Kotaku says a branch of Amazon (read - not the US) has a date of the 20th up. Make of it what you will.
