The larger questions are:
• How is Adobe going to make the transition to Animate in terms of browser plugins?
• And how are websites which currently make use of Flash Player going to do so in a reasonable/workable fashion?
Adobe makes their money from the developers so Animate could be just an HTML 5 development tool. There would be no need for plugins, any HTML 5 complaint browser would work. That would save Adobe a ton of money developing plugins they give away free. Sounds like a sound marketing plan to me.
Websites currently using Flash will have to convert to HTML 5. There are fewer and fewer Flash dependent sites because they freeze out a huge number of iOS users and don't really play nice with any touch based smart phones, tablets, etc.
Not even Adobe can ignore 60 to 80% of the internet market.
