I'm waiting.
They have that 3 year $4 per month deal. However, that is just Disney+ alone.
The $13/month deal will come with Disney+, Hulu, and ESPN.
I already have and use Hulu for $13/month. This means that if I get the $4/month deal, I will be paying $17/month for Disney+ and Hulu, but not have ESPN. So I'm better off waiting for the $13/month Disney+ deal and having all 3 for cheaper.
I'm pretty sure this is what quanch is like in real life, except not ironic and satirical...
