I believe it reopens Aug 21. My understanding is there will still be a teppanyaki side & they are combining/updating the Tempura Kiku & Matsunoma Lounge. This area is what will have more sushi offerings.
If the powers that be are smart (IMO), they will expand the teppanyaki side & move it to the front of the pavillion to take advantage of those great views & move the lounge/sushi area to the rear.
