There has been some talk of a new animated series should the next movie, Star Trek Into Darkness
, be successful. But it's years off if at all.
(just ignore the crap about the comics being canon, Orci refutes it as just placating the pushy interviewer in the comments)
FWIW, there was an animated series planned in 2005, called Star Trek: Final Frontier
, but it never came to fruition. Info, the first script, art (OMG look that that Enterprise
) and storyboards here: www.zeroroomproductions.com
