The Surface Pro is still only available in the US and Canada, right? I don't think 400k (if that's actual sales) is a bad start at all, but it will require at least one technology refresh before Windows 8 tablets can become really popular. My expectation is that Win8 tablets will gain a lot of momentum over the next two years, taking over a large part of the Ultrabook segment.
I'm not surprised about Windows RT faring poorly, though. It just doesn't add anything significant over Android or iOS at the moment while being less mature.
