From CBR:

In a bombshell move, Disney will expand upon some of its most popular characters from the Marvel Cinematic Universe with its forthcoming streaming service Disney Play.

As reported by Variety, Disney is developing a slew of Marvel Studios projects which would include both a Loki and Scarlet Witch television series. As though that weren’t enough, the report claims the streaming service will serve as a home to series for other MCU characters that have yet to appear in their own solo films.

Both Elizabeth Olsen and Tom Hiddleston are expected to reprise their roles as Scarlet Witch and Loki respectively. While these projects are still in the early stages, each series is expected to receive between six to eight episodes. Like with the first season of Agent Carter, Marvel Studios president Kevin Feige is expected to take a hands-on role in the development of each series, with the budgets expected to be “hefty,” not unlike a studio production.

Unlike the other Marvel TV shows, which are produced by ABC Studios and fall under the Marvel Television umbrella, these series will hail from Marvel Studios. In other words, any fans hoping for any crossover between these Disney Play shows and Agents of S.H.I.E.L.D. or any of the Netflix properties probably shouldn’t hold their breath.

Neither project has a writer at this time. While plot details are still being fleshed out, it’s said the other core Avengers will not show up in these series. Instead, each series will focus on “second-tier” characters from the Marvel Cinematic Universe.

Disney Play is expected to launch sometime in 2019.
Will be interesting (I just hope this service is international!). TV shows really allows for characters to be fleshed out more than two-hour movies (well, when the writers knows what they're doing).
