It's not really news, but yeah Flash isn't going anywhere anytime soon.
But yeah, nothing comes close to what Flash has given us. The good news now, is that with WebAssembly, solutions for gaming will not form in terms of plugins, which means, there won't be a way for browsers to reject them.
So I have hope for the future. If you're a game developer and love to make web games, this might be a good technology to research.
