I would have voted "Yes, but it doesn't matter to me because I won't use it!"
However, I just voted yes. I think it will be back, but less attractive each year. I think you've already seen the start of that this year, with the extended periods of availability for UK and Bounce Back, shortened availability for the "public free dining," and also with the menu exclusions for free dining.
If I had to predict, I would predict that "free dining" will be for a
shorter time than either the UK or Bounce Back, that it will only be available at
Mods and above (as already announced for the UK) and that there will be
further menu exclusions and possibly some restaurants who don't accept free
DDP.
OTOH, if we get really unlucky and a hurricane hits WDW this year, that could change radically. It all depends on their occupancy -- don't forget that free DDP is exclusively a lodging promotion, and they are not going to give away one penny more than they need to to maximize profit.
