My guesses:
1. If it doesn't change from the current process you will be able to use You Tube TV or Sling (or possibly some other streaming service) as your sponsor with a digital code. You might need to pay an extra fee like I do for ESPN+ via the ESPN app. You will need to have wi-fi service with a sufficiently fast download speed if you want to avoid buffering issues. I use a service that gives me 7-8 Mbps download speed for $99/month--good enough to stream well on one device at a time which is all I ever do with almost no buffering issues. My provider also offers a faster download speed for $199/month which would allow more than one device to stream video simultaneously.
By the way, at the moment, I believe U-Tube TV ($40/month) has the most sports stations included of all the streaming services. With ESPN+ added I am paying $45/month total (U-Tube + ESPN+) and I can watch any ESPN3 or AACNXtra college football or basketball game live and/or watch the replay later if I miss a game I wanted to see live. My total wifi plus TV bill is $144/month. For comparison, I used to pay $210/month for a combination land line and DSL from the phone company plus Dish Network w/sports pak and got worse sports coverage and experienced a wifi download speed too slow to even stream games on the computer without constant buffering issues.
2. I don't know about blackouts of home games since I don't live in the Pittsburgh area. I am not expecting that to be an issue for me.
