There is almost no way the RSNs are coming back, Dish is making increased profits by getting rid of them without lowering prices and not that much loss of subscribers.
YTTV became profitable when then got rid of them, did not lower prices and they are gaining subs ( not many Live TV providers are gaining ) without the channels.

This is behind a paywall, but the part I wanted to share here with regards to Dish is the updated costs of the RSN's individually. Purely from a financial basis you can see why Dish dropped them. Here are some of the highest reported costs for an RSN for each individual subscriber:
BS Arizona: $8.38
BS Ohio: $7.84
BS Detroit: $7.76
YES: $7.20
BS Wisconsin: $7.15
Even BS Kansas City, which I believe only covers the Royals, is $5.82.
Dish starting dropping the RSN's in 2019, and looking back to 2014, which would have been the 2nd to last or the last group of long-term contracts Dish signed for the RSNs, only 7 RSN's total cost more than $3.50 per month.
