WGN (Channel 9) will have 35 regular season White Sox games and 40 regular season Cubs games, no playoff games.
It's WGN America that is definitely a sticking point.
"Tribune Media is also seeking more clearance for WGN America, the former superstation that has been converted into a full-fledged cable network, with original programming and no local news or sports. WGN America reaches 80 million homes across the U.S., up from 75 million four years ago.
In its release, Dish cited the elimination of Cubs baseball broadcasts as affecting viewership for WGN America, which it said was down 20 percent since relaunching as a cable network. Dish also said many of the shows on WGN America were available on other channels carried by the satellite provider."
"Consumers shouldn't have to pay twice for the same programming," Schlichting said.

It seems possible to me the locals channels are being held hostage because they are bundled with WGN America and that dispute keeps the contract from being agreed to. It may not be quite that simple but it explains locals being off longer than the usual time period. (So two things DISH objecting to the asking price and objecting to it being bundled with locals)
