I voted "Other."
As things stand right now, I don't have many 3.X PCs worth converting. I have some unplayed concepts, to be sure, but nothing I can't kit out in almost any FRPG with a bit of thinking.
My big conversion concern would be over a bigger gap than that.
My oldest running campaign dates back to the mid-1980's, and we haven't converted from the fusion of 1Ed/2Ed it was set in. I was just this month sitting down to work out the difficulties of translating a high-level Drow Druid/Ranger/Magic-User (very pre-Dritzzt, thank you very much) into 3.XEd- and there are difficulties a plenty- and this 4Ed announcement comes down.
*sigh*
