SVG delivers today too. Maybe not on the web at large, but for app builders it's most definitely there and being used. Few websites need to be complex apps (and when they do, what's an extra plugin?), whereas intranets are using those more and more frequently. That's where SVG is, and is today. In my five last contracts I saw it used in two government intranets and two large company intranets, and only one of those contracts had anything to do with SVG. I have seen no use of SWF there, nor any intention to use it.
The Flash/SWF integration is only interesting for animations and the kind of Hello World apps that one can make with MX. SWF has good libraries, but we're still waiting for the kind of integration that you have between any XML publishing framework and SVG.
