Flash market is still there, and it's growing. Hard-on-3D browser based games are extremely sparse with business opportunities, as are HTML5 (WebGL, Canvas, plain old school js) games.
Unity player is seeing huge growth, but that's peanuts in comparison to Flash plugin availability. HTML5 games need monetization strategy that ain't just "slap a multiplayer and process most of it on backend".
Thing is, Adobe is a corporation. They think business first, technology second. Market is there. Plugin availability is there. Tools are there. Developers are there. Wtf?
And that's why Adobe doesn't make sense to me with all they're doing with Flash. At all.
On a more personal note, another wtf! Flash enabled huge infusion of creativity on web, way of expressing in much less contrived ways than available. Made you experience web you remember fondly from not so far long ago. Still does. Remember that. Only then move on.
