I've said it before and I'll say it again: why on Earth would CBS green-light a post-Nemesis, prime universe series, when the Abrams films are way more popular and filled with sets, props, costumes, CGI ships, etc. that could all be reused for a new nuTrek series?
1. I don't believe live-action is ever going back to the Prime timeline, it doesn't make any sense to do so.
2. The Abramsverse sets would be owned by either Paramount or Bad Robot (depending on their agreement). If/when CBS decides to do a new Trek series, they would either have to start from scratch or rent the sets (if they still exist) when they start up.
