I finished listening to the "Inside the Truck" podcast from Jan 5. My speculation flows from the information within that.
Only one camera crew will be at games this year supplying both the home and away video feed. This feed will feel a lot more like a national feed than we are used to for regional games. (think 60% home 40% away bench/player/GM focus)
Home commentary will be done in arena.
Away commentary will be done off monitor from studio or a truck in away arena.
I suspect that Sportsnet will only have a single broadcast. e.g. if Oilers are playing Canucks the will show the exact same broadcast for both teams. This is similar to what Edmonton/Calgary get a few times a year, but it will likely feel a lot more like a HNIC broadcast.
I suspect that we may see a crews based in Vancouver, Alberta, Toronto for the year. I have not looked at the overlap of Cal/Edm home nights but I suspect there may be single crew assigned to produce home games in Alberta. Away games may be a bigger mix of Sportsnet crews.
HNIC games broadcast from Winnipeg, Ottawa, and Montreal may be called off monitor in Toronto or Alberta.
