We recently learned that Disney+ will offer a $12.99 bundle that includes Disney+, Hulu, and ESPN+, but there is a catch. These will be limited versions of Hulu and ESPN+.
Earlier this year Hulu upped the number of streams from one to two on its limited-commercial plan. (Hulu rarely had enforced the one stream limit before this.) Now if you get the $12.99 bundle you will only get one stream.
