A source has told US video game blog Kotaku that the basic (white 8GB) model of Wii U is being removed from Gamestop shops. According to an internal memo all basic models are to be returned before June 18.
Meanwhile, Nintendo of Japan are introducing a white premium (32GB) model on July 13. Surely a sign the 8GB is on its way out.
There is no official word, but perhaps Nintendo will clarifies things during E3 next week.
