Whoever predicted Star Tours would go away right after GE opened were wrong. It's a whole another conversation about "insiders" who they are, where they get the information, and why they choose to say what they say. Suffice to say I don't put much if any stock into what gets said from non official sources. The thing is, the Star Tours leaving rumor never made a lick of sense. TL redo is years away and has always been years away if it happens in the near or medium term at all. If you've been on or know the Iron Man experience at all, you know that cloning that for DL was/is not going to happen.
If you are going to tie it to being the same IP, same type of ride system, and the same park; then yes this is unique. I was talking about ride systems in general. People are arguing the ride system used in Star Tours is obsolete. I disagree. That is where I was coming from. Disney reuses the same ride system constantly. Each time they refine and make improvements on it. It doesn't make the older system obsolete.
Building a ride simulator that does different things than Star Tours doesn't make Star Tours obsolete as a ride system. It simply does different things. In fact, some prefer the Star Tours ride system as they don't like the interaction part. This allows guests to experience one of both types of attractions within what may be seen as the same genre of ride system so to speak.
As a side note, I feel that like everything else attractions will become more specialized and try to hit niche groups. MF is an attraction that aims to appeal to those who like interaction in their ride experience. Those that don't want this type of experience won't ever like MF. However, a growing number of people do and Disney has to build attractions for those people. Those that want a more passive Star Wars experience can go to Star Tours. A fundamental flaw of Galaxy's Edge is that it went all in on interactivity and those that want a more passive experience were never going to like it. They needed a mix so those who want to sit back and be entertained can do so. Even ROTR is trying to make you part of the story.
