I'm still baffled why they don't just go ahead and bring it back.
The dome screen is still there and I've heard the fog machinery is still there for the faux fire, just disabled.
If the issue was projector quality, or an issue with mechanical harddrives (so I've heard), we've definitely got enough advancements to bring it back.
Although they did remove some of the set to fit the new projection better (remembering the days when the current video was literally a TV mounted on the wall and then a smaller projector LOL) so at this point, I think they won't want to spend the money.
