I know that's the plan, but it has to be replaced with something. Also, now that I think about it the Iron Man Experience at HKDL is completely based in Hong Kong so it would require more than just cloning the ride here in the Star Tours simulators if that did happen (which I agree is doubtful).
I seriously doubt they would keep the Star Tours ride when they finish Star Wars Land. I can't be the only one who sees them closing it. I would think it would be confusing to the every day guest at the least.
