Cryptic is transitioning to Deca Games within Embracer.
Deca is currently staffing up, and their staff are being trained to work on the Cryptic games.
In the long term, it is anticipated that Deca will be handling development, with Cryptic functioning in a "support role." They're honestly not sure what that looks like in 4 years' time.
None of the Cryptic games are being sunset, and their Star Trek license for "several more years."
The reason for moving these games to Deca is that they want to keep them going for as long as humanly possible.
Embracer regularly identifies STO as one of the top-performing games in its back catalogue, and it doesn't make sense to sunset a game that still "has gas in the tank."
There are no "known" changes coming to content release, frequency, etc. The current release size can be used as a rough indicator for future releases.
They are working with Deca games to teach them what kind of content they think the audiences of their games enjoy and expect.
Here's a screenshot of the near-future STO roadmap:

The new ship bundle scheduled for May is a T6 Dyson ship.
