I have the same experience as the OP, 2 or 3 of my blog sites that were kicked in to touch have come back to their original (or in one case better) positions than before the 'panda penalty'. I've done nothing to the sites at all but 2 of them did have a forum signature which I've removed. Other than that no changes were made.
Site came back Tuesday, disappeared for a few hours Wednesday but then they've returned to good positions again. Oh, these are UK sites too - and I've heard lots of people talking about changes on Tuesday this week.
