The Tools Are Coming
I would expect designers to go after the SVG format, rather than the Canvas tag (which is basically a programmable graphical surface). SVG is supported in just as many browsers as Canvas and is more powerful.
There are already tools out there (Inkscape, Adobe Illustrator) and I've been helping a web-based tool: http://svg-edit.googlecode.com/ - it's a start
