So they're releasing the updated 4K TOS movie set with V and VI (They're also available separately for anybody who got the original set, which for some reason only included the first four films) as well as the new version of TMP's director's cut (Which includes some new effects/sound fixes in addition to the 2001 FX) next week.
Also the Light and Magic series has some Star Trek stuff, although it's mainly focused on the Genesis CG effect.
