Here is a lineup update I put together with information:
The new Flex Package is now available on Dish for $34.99 a month. Add-on packages are available--Locals Pack, Regional Action Pack, National Action Pack, Kids Pack, and News Pack are $10 each. Heartland and Variety Pack are $6 each, Outdoor Pack is $4. You have to call customer service to the Loyalty department (866-974-0769) to request this package. They aren't posting it anywhere yet and no lineup is available online.
Note: No Fox Sports RSN is available at this time. Multisport w/Redzone still requires Top 120 Plus or higher to add, hopefully this changes in the future.
Here is the lineup based on what I am receiving (excluding Freeview channels):
