Are there any 7-to-8inch Windows Tablets? Because I want one.

I'm interested in something VERY similar to the iPad Mini... only running Windows RT. I want it to be $329-399 and have amazing build quality. I haven't used Windows 8 yet, and think this would be a good way to get my feet wet. Plus I'm looking forward to next-gen features (second screen, gaming controller, etc.) that would hopefully be unlocked with the Xbox 720. I haven't seen anything so far, nor have I even heard any announcements. I'd LOVE a Walkman or Lumia-branded iPad Mini competitor (shit, even a Surface Mini) running Windows. Have there even been so much as rumors/leaks of such things? Bueller?
