I don't think we should ever "expect" a ride to have Hagrid crowds. Mario/Nintendo could possibly come close in Japan. Remember the wait that USJ had simply for The Flying Dinosaur? If a ride like that gets 7-8 hour crowds, I expect Mario and the gang to get real close to Hagrid considering how big Nintendo is in Japan.
Here in the US, however, I don't know of anything that will have Hagrid-like crowds on the current slate that we know of. Nintendo is opening along with a new park here as
@Scott W. said, so that makes the overall crowds to one specific area less. So yeah, Hagrid is not a good measuring stick for anything
