I haven't heard anything I can share.
It seems reasonable that Disney will match hotel room supply to demand. Recall that Dixie Landings closed after 9/11. It's possible that a bunch of resorts open later that others, especially if parks are capped at 50% occupancy. Staffing may be an issue, so having to staff fewer hotels would also work in favor of that strategy.
In the case of DVC, they've all but said that they expect demand to exceed supply. I wouldn't be surprised if some DVC owners are offered standard hotel rooms for their stays, if DVC resorts are full. For example, if you can't get your OKW studio, would you take a room at Destino Tower instead? That would help Disney redeem DVC points and get people on site.
As far as what Disney has done in the past, the
Wayback Machine captured Mousesavers' discount page in January 2002. Here's a table summarizing the discounts back then, and what the inflation-adjusted prices would be in 2020:

Adjusted for inflation, some of those early 2002 discounts aren't as good as the ones we saw 18 years later - January and February of 2020. The two rightmost columns capture the lowest rates we've seen on Priceline in 2020 for select Disney hotels.
All of those 2020 discounts are substantially better than the 2002 inflation-adjusted discounts. In fact, all of them are better than the non-inflation-adjusted prices, meaning they're at least 43% better than the 2002 discounts ($1 in 2002 = $1.43 today).
Let me know if this doesn't make sense.
