That's just bull. Its on Macs now you know? I mean I can't believe Microsoft is discriminating that way. Boy, next your going to tell me that BeOS isn't available either...
It's not Microsoft's fault - it's Nintendo's fault. The Wii U is just too underpowered for the awesomeness that is Windows 8.
Besides, if we did get Windows 8, we'd probably miss out on the DLC that's coming soon to make it usable.
