No, that's not 'common sense', that's knowledge of a specific situation. A person without this knowledge would perhaps conclude that "People Mover" route means that it would be on the old People Mover track. It seems that Miceage doesn't care to address the practicality of such a project.
Nonetheless, you avoided mentioning that there is not enough room on "People Mover route" to put in a bike coaster. Simply not enough clearance, or space for banked turns, and they have to do major construction, and likely demolition, on the Star Tours, and buildings east of there, including near/in Space Mountain, and Innoventions. Some buildings could well have to be removed.
What "bike" from Star Wars are they using? Seems very far-fetched on a creative basis.
I say bogus rumor. Iger's crowning achievement will be Shanghai Disneyland . . . a massive new castle park with space for a second park. He also greenlit Avatarland, Carsland . . . don't see him asking to "turn on" the money spigot three years before he leaves.
