According to http://www.facebook.com/note.php?note_id=328795820483403 (which is the official Samsung channel) ICS should be on the following tablet devices now: GALAXY Tab 10.1, GALAXY Tab 8.9, GALAXY Tab 7.7 and GALAXY Tab 7.0 Plus.
That's from December 2011, but sometimes there oddities in the rollout, especially with regional variants.
They said that then, yes. They have not, however, actually done the rollout, at least for the Galaxy Tab 10.1. Retail, or the I/O giveaway variant, for that matter.
