The most intersting aspect of the Windows minisaga is whether ANYONE, including Microsoft, releases Windows RT on any sub-10" device. If no one does, then that means Windows RT is dead. Actually, it's extremely doubtful an OEM would do this anyway, as only 3 are still in the Windows RT biz at all right now (besides Microsof themselves).
Furthermore, Microsoft would be insane to release a Surface Mini with WIndows RT if everyone else releases with Windows 8, because it would once again create chaotic confusion amongst consumers, who would once again be offered confusing options, and thereby elect to avoid the Windows mini category all together, unless that is, the OEMs spend massive amounts of money explaining why THEIR tablets are the ones people should be buying, and even that might not be enough if Microsoft themselves counter promote a Windows RT mini.
