Didn't see it mentioned here yet. Star Trek on Blu-ray finally official:

I was going to hold on to my TOS DVD box sets due to the updated special effects, but unlike the HD-DVD version, the Blu-ray version will present both the original and updated effects via seamless branching. And the price is much saner than the HD-DVD release was.
Wrath of Khan is getting a new transfer from restored elements and Undiscovered Country is being presented in its proper 2.35:1 theatrical aspect ratio (the DVD release was 2.0:1). Again, I'm stunned by the price also.
I'm really looking forward to these box sets.
