There is not enough interest in EA anymore as we can see in the forum for which I use to have a large amount of questions every day. So the chances the development will resume is pretty slim and since the focus in on Animate CC and EA is hidden in previous versions, it is unlikely that the EA community will grow. Too bad because there is not really an alternative that is as good, even Hype which is only for Mac.
For windows there is Google web designer, discovered recently and I'm giving a look these days, but I do not think you can compare to the excellent Edge Animate ... also able to build an entire site in it. I not yet know if it's possible with Google web designer.
It 'really a bad thing that has abandoned adobe Edge Animate. We make a petition of signatures? Let's send mass email to all adobe? Unity is strength. So we should make us feel, because animated edge likes to so many people.
Today starting adobe edge animate appeared the survey window with a scale of 1 to 10 how likely would you recommend with edge animated? Unfortunately over 10 I could not vote, and I had to settle to put only 10. Then I also added a nice feedback hoping and almost even begging to reinsert into the fantastic adobe package to fill that big empty html5 Sun div which now afflicts the adobe suite .
Maybe some minimal hope that edge animated return there, otherwise I think we would not have entered the poll, so I recommend you do not close that window, but the dates one vote and also write a comment. It 'very important for the future of animated edge.
