The next Santa Fe looks longer and larger than the current one, but far more agile than Highlander and much lower than a Pilot. I'm sure the interior space won't measure to the Pilot either.
It'll be what it is... something a little different. Right now I'm thinking of the Santa Fe as a Suzuki XL-7 with a powerful engine, much better handling, more visual cleanliness and sportiness, and a modern Hyundai interior.
But photos can be deceiving where size is concerned.
