They more or less did. Check out TrekCore's screencap section and you'll see. The new effects are both obvious, but at the same time look so close to the original versions that there is no problem. That said, I wouldn't mind having the bonus stuff on DVD. I'm referring now to the audio commentaries and the extended version of the second season Data on trial episode (I'm actually drawing a blank on the title, of a TNG episode no less, can you believe THAT.), because I will never upgrade to Blue Ray. It came out WAAAAAY too soon. DVD is just fine, thank you.
