It lists the principle crew (our fearless seven), but no mention of who will play any of the villians. It does give a brief plot overview (at least the beginning of it).
Oddly, there’s no mention of Wil Wheaton in this release, but there was in a previous release. His website says to watch for him in Star Trek X. We’ll have to wait and see. There’s seems to be some really bad blood here (check out his FAQ on why he left).
I’ll try my darndest to keep everyone up-to-date as I get reliable information.
