You will get BTN if you're in the #footprint.
Hi Bob, upon further review, the out-of-market Big Ten Network feed, which was carried on the Sports & Entertainment package in non-Big Ten states, was dropped, however, customers in Big Ten states in their regular channel line-up, will still continue to be available. -JRW— ComcastCares (@comcastcares) April 12, 2018
Update: Spoke to a Comcast rep who said Comcast customers in the state of Michigan will still have BTN.— Nick Baumgardner (@nickbaumgardner) April 12, 2018
Anything beyond that is TBD. But if you live in the state and you have it, appears you're OK.
