Yet, they're already on the 3rd revision of Curse of Strahd already, and 2nd of the Tiamat adventures.I think releasing an update of any previously published 5e adventure would be the absolute dumbest thing WotC could do in the next year, since they've stated over and over again that the old stuff will work just fine.
I don't think it's unlikely they'll go back and redo some of the more popular ones. At the least it's a chance to do a reprint for those who may have missed it the first time around, and update some of the monster stats/errata while they're at it.
