The process of putting TOS in HD was completely different since it was shot and edited on film. Some of the people who did the new FX might be working on TNG, but the major component of the TNG project is finding and re-editing the raw footage. That sounds like a highly specialized set of skills. If another series that was edited on tape wants to do something like has been done with TNG---those folks might be working somewhere else for a very long time. And I was never confident about DS9 on Blu-ray and that press release didn't give me an ounce of hope. I assumed it was a poorly worded bit of hype.
