I wouldnt be shocked by this at all. There's been little news about it as of late and it was strange that we got a SWGE opening date but not for this. I think this might have to do with all the issues they're having with the trackless tech which is also behind the delay with RotR.
I don't know why they seem to be having this problem in the US parks since they have this in Hong Kong, Paris, and Tokyo without any issues.
