So the major manufacturers that were there had pretty good displays, with good selection. Toyota had a lot of floor space, and the Prii got a lot of attention from show goers. Pretty decent section too for GM, they even brought the Equinox EV (roped off though).
Demand vs supply shows though - the hot-selling Sportage had a single gas model on the floor, and one HEV set on a stage where you could not get near it.
Nissan had a single Ariya, an all-black fwd mid-trim and for me that was the revelation of the show. It's right-sized, and offers a flat floor upfront. Prices are way up there though.
