I kind of still feel you're splitting hairs, but to your credit, I think what makes the promise of "Epic Thrills Coming" not just be an event is both the odd mechanical bird logo (which seemingly does not tie into any known event), and the color scheme, which again does not match any known event.
Now, is it guaranteed to be a roller coaster? No. But this is a park whose main distinctive feature is their coasters, and the space they've cleared is enormous (as it also *seems* to include where monorail track was cleared all they way by Swashbuckler).
While I certainly may end up surprised, I can't think of a single event or flat ride or building that would require that much space. As they say, where there's smoke, there's likely a fire. What isn't known is the type, style, or maker. There is a surprising (and curious) absence of leaks and substantial rumors. A few things popped up ages ago (I seem to recall hypercoaster and motocycle coaster being the two leading ones), but nothing has been followed up on that I know of.
Still, to me, it seems pretty certain it will be a coaster of some kind. You're free to disagree, because, to your point, no one really knows for sure.
