Surprisingly enough, this one hasn't gotten a lot of attention online.
Treadstone just got its first official trailer online. Its a spin-off TV series set in the universe of the Jason Bourne films and will follow a bunch of other agents from the Treadstone project that Bourne was a part of.
Here's the trailer:

And here's an interview that the showrunner did with EW:

The trailer looks good, though it doesn't reveal much. Personally, I'd rather just have Jason Bourne back on-screen, but in his absence, exploring the Treadstone project is the next best step.
I feel that this series could be successful at what The Bourne Legacy, starring Jeremy Renner, tried to do years ago. That movie had some great ideas but ultimately didn't click because it tried to cram too much world-building into a single movie without much of a compelling narrative. I think a TV series is really a much better medium for expanding the universe of Jason Bourne.
