Soon, but how soon remains to be seen.
Flash will be a "Flash in the pan"!
The reality is simply technology changes, and along with it, many parts and pieces, and Flash is just one of those pieces.
Hell HTML5 will likely be replace. By what, from who - who knows, but they will both be replaced.
Hell the iPhone, iPad, iPod won't be the next big thing as they are already here. It's evolution - shit happens. We all use to be fine living in the current time, but now, many of us, expect and want "The latest and great NEXT thing now. Which means, it's not the latest and greatest things, because the NEXT thing, is in fact, the latest and greatest.
I for one, would LOVE to have the world and technology slow down for just a bit please. NONE of us, fully use the capabilities of any of our toys right now, yet we want them to go fasters, do more, use less energy, do better, cheaper, cleaner and better then the other guys.
But hey, we should all enjoy it while we can. Because it and we, won't be around for ever.
