Recently someone referred to a Cocoon 3.0 that will eventually come. I think that it will eventually come, though not for some time. I have some thoughts that were inspired by experience with another group of developers, but I think that they can apply toward whatever Cocoon 3.0 might become. You can read those thoughts here:

While I have been working mostly on the client side for the past year and a half, when I come back to Cocoon every now and again I have a fresh perspective. Cocoon is founded on some simple concepts, but it has ballooned into a huge beast.
Perhaps that essay can even help current endeavors. I am a fan of Cocoon, and for a time even helped build it. I currently don't have time to do active development on it, but I still want to see it succeed.
What I wanted to remind everyone is that developers are users too. They should receive just as much attention as the end user. Keep things simple, learning from your experiences.
