IIRC, wasn’t it mentioned that they would be and it partially has to do with programming for the new shows?
I mean, I wouldn’t imagine that we’d see the preview/teaser footage that we did which appears to include lasers if their absence had to deal with safety reasons or clearance from an AHJ.
Around the 27-second mark of the video in the link below, the manta ray appears to be created from lasers on water/mist.
See the first video of Harmonious shot from inside EPCOT.

Unless I missed one of the insiders allude to there being issues with the use of lasers, I wouldn’t get too worried. Just my thoughts for whatever it’s worth.
