Not sure why you are waiting just root it and do it yourself. Since I was rooted I manually updated to 3.2 the day it was released.Still nothing for the Canadian XOOM ... terrible support by Motorola.
From clockwork recovery you can mount the internal storage as a USB deviceHo so I am having the same issue trying to lock my Motorola Xoom wifi(601) to return it to stock so that I can do the the Honeycomb updates(such as, 3.1, or 3.22). Have you resolved the issue yet? The main issue for me seems to be that I cannot flash a new rom update onto my wifi xoom since I have no external sd card support. So does that mean there is no way of me getting the Honeycomb updates for my Xoom until I get a special usb converter cable?
sucks is such a generic term...The update sucks, at least for my vanilla device stick to GB as long as you can.
