An animated series isn't my first choice but it could be excellent a la The Clone Wars and it is far better than nothing. At the very least, it would demonstrate that Star Trek is perfectly viable on TV and keep the franchise alive in that medium. I still think that if Game of Thrones can make it on premium cable - nerdy content at a high price tag - then why couldn't space opera do the same?
The voices can also follow TCW, use the movie actors when feasible - Samuel L. Jackson must be cutting them a deal based on his love of Star Wars - and use voice actors for the rest. I like the guy who dos Obi-Wan better than Ewan McGregor and Anakin is good too although he does sound a bit too surfer-dude-ish at times.
