I think, like many relationships, Hive has hit a sort of plateau. We're fine and we tolerate each other's company well enough, but it does seem like people have lost the excitement that was in Krakow.
Then again, I'm not one to speak. I'm only a blogger. I struggle to follow the techy parts of the blockchain. Still, I remember a lot more struggling a few years ago. Now, it's just coming here because it's what we've done so long. I realize I'm not as excited as I used to be about what Hive could become, though still in a placid (though deep) way, happy it exists.
That being said, I'd say yes because it's a closer answer to "it could be again" than saying no. Only time will tell. If it's in Europe, maybe see you at the next one :)
