I haven't heard anything as well. I tried to get MS reader for my poor Q1 and it insists on the origami pack to be installed, and of course the pack fails. So I have a nice little "tablet" with a horrible experience with reader. Expecting heck to freeze over before I see one, though. Unfortunately most of the touch packs are OEM only now, so even though they demo'd some really nifty things on the Today show, it was a little misleading because you wouldn't get that experience if you upgraded.
