Yes, I have heard this too. I would imagine T16GEM, that installation of an elevator in the front pool would not be started for probably a year at the earliest. I would be willing to bet that Seaworld closes down the main pool in a very slow part of the year, like mid January, and hosts shows at the current Dine With Shamu area while the front pool is renovated. Unfortunately, it may be a year and a half maybe even two years before we see waterwork in shows again. But atleast we have some sort of a timetable now.
With that said, I wonder if waterwork will be performed at Dine With Shamu shows, since they are installing this floor now in that pool. I could see trainers doing a limited waterwork session for Dine With Shamu guests. That could be something very cool to see.
