I somehow feel that Samsung will pull through, but I could be wrong. However, on the other hand, I'm somewhat shocked that nothing has been announced just yet.

There have been no updated re: Tab moving to v2.3, which seems logical, considering that the Galaxy S line of devices are all getting it, and the Tab has very similar hardware. So if not, 2.3, what? I think that the Tab will receive some sort of update, though exactly what remains to be seen.

speculation:
My gut says that Samsung is still hard at work on this, considering that HC seems 'optimized' (read: slow on anything other than) Tegra 2. But it's better not to set expectations if you know they won't be hit and so the announcement will imply that the roll-out is imminent.
