Seems purdy cool.
So far unimpressed... and the demos are not that hard to replicate with jquery.
However, I would be very happy if this becomes more powerful.
did you look a tthe source it produces? It's easily extendable with jquery, and includes jquery,
Then why not just start with jquery?
Until the tool rivals Flash 5... then I might use it.
I just downloaded Edge Preview 4. It looks like it will be pretty cool... and a great strategy for Adobe.
I have some questions, though. 1) Can you link a symbol to an object like Flash CS5.5? 2) Are we stuck with the timeline again?
basically do we have to go back to Flash 3 or 4... and start over again?
I'd say more like flash 5.
It's much more like flash 5. BUT, we have the browser canvas. SVG works exceedingly well, and is underutilized (ignored! and yet it's awesome. ) for vector drawing on the web. IE8 of course blows donkey. Safari, oddly remains the caveat with SVG if you're ignoring IE8, but there's some tricks you can do for safari to kick it in the side and get it working. We didn't get bitmap access until flash 7 if i recall correctly. So it's not quite accurate to say we've started from scratch. It's more that flash has a decade of lessons learned to teach the browser makers how to deploy rich media. As well, since most of us here come from a flash background, we're about 3,4 years ahead of everyone else in terms of understanding what's possible with what browser makers are offering right now. There's opportunity to really blow some clients' minds.
I am not sure what you mean by link a symbol to an object. Perhaps you mean to define a class which extends a library symbol? Edge uses jquery. Therefor all of your objects produced by edge have easily findable IDs and easily extended by code. As well all of the animations are triggered by timers. So while you build the animation in the edge timeline, all are accessible in human readable jquery code in the output for easy manipulation.
Where things get tricky with edge is abstraction (pulling an edge animation into a larger project) and also converting edge objects to liquid layout. Edge currently can only do absolute height and width. However, the css and jquery produced by edge is human readable, and both issues are easily solved with some css know how. Edge remains the fastest way to prototype animations as well as build animations for larger projects.
I think Edge still has a long way to go due to the css and absolute size issues, and i am glad they're not charging for it yet.
My latest project's homepage uses all of the above, bitmap canvas, svg, jquery and prototyped in edge. http://cityforward.org/
thanks persist, you boiled it down for me, very succinctly as usual. Of course some more questions...
That IS what I meant by linking a symbol to an object (or class)
So regarding the graphics... is SVG part of the canvas tag or an overlay or something completely separate?
Also are there any cool SVG editors out there? Inkscape come up on google, but cannot create animated SVG content. OR do we just create the graphics and animate with JS?
SVG is a separate beast, served as, or created on the fly as XML, which jquery is very good at manipulating. The canvas tag is different. So think of SVG as the general graphics drawing tools in ActionScript, lineTo, fill, etc.
Canvas in the browser is akin the Bitmap Object in Action Script, which has it's own setPixel methods.
Here's where things get tricky though. Canvas' drawing methods in javascript look and act very similar to the ActionScript vector drawing tools! So it's easy to mix them up.
Adobe Illustrator is the BEST for drawing optimizing SVG for the web, with multiple SVG spec output. You might google SMIL, which was originally intended as the media/animation specification for SVG. I do not currently know where this spec is with the w3c. 
To answer any deeper questions, I'd output some edge examples and simply look a tthe source and how they're animating things.
