It certainly doesn’t look like an easy work around
JavaScript is easy!
SVG is easy!
HTML/CSS? easy!
Design? Hard. So if you’re any good you’ll be OK whatever.
For businessy stuff, if I was a Flash developer I’d start looking at things like Ext.JS/Sencha, and think hard about my future training requirements.
For the design driven stuff, I think that designers locked into the Adobe Photoshop/Flex/Flash infrastructure will ensure that magazine/branding style sites will continue to get made in Flash for a little while yet, but no-one actually uses these sites do they?
