According to Gamasutra,
Atari announced in an earnings report today that it is looking to sell
Cryptic Studios, having "determined that external development creates
more flexibility in the changing marketplace." In the meantime, Atari
will continue to support all current Cryptic projects, including
Champions Online and Star Trek Online. Development on Neverwinter will
continue as planned for the time being.

Cryptic Community Representative WishStone has addressed the news on the official Star Trek Online forums:

"Right now I have no further details other
than what has been mentioned elsewhere. Support for Champions Online
and Star Trek Online will be continuing as normal, our staff is working
hard on their projects (and the folks from the Champions team deserve
an extra cheer for their new stuff by the way) and there are no planned
changes to the way any of our games and projects will operate.


So Stormy is here, I am here, Dan and the gang are here, your GMs and QA
staff are working hard. It sounds way more dramatic than it actually
is."

According to WishStone's post, this move should not affect players of Cryptic's games.
