From Variety:
Disney+ will launch in the U.S. on Nov. 12, 2019, and will cost $6.99 per month, the company announced — nearly half Netflix’s standard $12.99 plan.

The subscription VOD service represents Disney’s biggest and most aggressive move into the video-streaming wars. By pricing it well below Netflix, the Mouse House is betting it can rapidly drive up Disney+ customer base with a mélange of content that appeals to multiple demographics, including movies and TV shows from its Marvel, Star Wars, Pixar and Disney brands.
In addition, there is an option for a year plan, which costs $69.99.

Disney+ will also include 'The Simpsons' and NatGeo programming(like Oscar winner, "Free Solo"), as well.

In my opinion, compared to the roll out of other online services, I think Disney+ has a decent launch catalog. My only gripe, is that most of the new 'exclusive' Disney+ films, sound like movies that were either nixed from a Theatrical run or the equivalent of a TV Movie/Direct to DVD.
