This seems kind of ready to me, why don’t they release this before Christmas?
I guess they still need to do a lot of work on the whole ARM and x86 Intel compatibility system so all the .exe files “just work” on ARM (virtualized, emulated, or whatever trick they are working on..), and for that a bunch of software optimizations still need to be done.
They should be selling or giving those ARM Powered Windows 8 Tablets away at least to the developers during the coming weeks and months? You can right now download Windows 8 Preview Edition at http://dev.windows.com but this is not yet the ARM version of that Preview software.
