So
this is a BM article but the sourcing is from The Wrap, about the proposed changes, in much greater detail: Emperor's New Groove coaster, but family friendly (intensity much closer to Slinky Dog instead of say... Velocicoaster), Maleficient boat ride, possibly using Pirates Shanghai tech, and then one other smaller ride and a dinner show.
Weird thing is that this doesn't exactly scream "Bigger and Better" to me, it just sounds different. The expectation was already that this would have two high level attractions, one of them being a coaster (rumored around Maleficent but that could just be assumptions based on the concept art). Pirates tech was due to come here eventually. This actually shares some similarities to the initial Galaxy's Edge plans, which also had three rides and a dinner show.
