Edge Animate is staying part of the creative cloud, so unless there is a major breakdown because of a browser update or something else, you can still use it. If there was a major breakdown, it is possible that we would get an update because that would make EA completely obsolete.
In the mean time, if you like to try other stuff and have the time (I tried them all) several choices to publish html5 and using the DOM unless Flash/AnimateCC:
Mac: Tumulte Hype
PC: Nodefire, Construct2.
