I think the flash games that exist on (example) pogo(EA) will continue to function. While not supported/changed, the users have a community and value that also uses the entire site. I am not in that boardroom, but to lose a user who plays flash games, is a user who now crossed the street to another store. Flash game or not. Just my thoughts.
They must rolling out something new. Built in obsolescence: helps keep the stock prices soaring.
They've been rolling out something new for years now: HTML5. You can do a lot more with multimedia content in-browser rather than needing a third party plugin. It's not forced obsolescence; it's just boring ole' progression and improvement.
The girthiest nail in Flash's coffin was that it was a never-ending security headache and it never managed to ditch that reputation.
