jeez why does everyone want animation tools in there - what a waste of time it would be if they concentrated on that… I’m all for the UV editing and better retopo tools though 
[you can see the uvs from another package btw - with uv check but to be able to both see and edit them would be much nicer].
Well, maybe i am a dreamer, but when i see nice things as posing tools, and rigging ones like in Zspheres 2 and also technologies like showed in the vids, plus things like Darukin’s plugin for animation in ZB, I just wonder how 3D could be with animation tools into an app like Zbrush.
It literally would revolutionarize the world of 3D making.
It would be the real next step!!
BTW, features like better retopo tools, paint layers with fusion methods, multiple textures per model support, UV tools and more are a priority for sure. I’d like to have those things in ZB4, actually. 
Also, considering that a young app like 3DCoat has those tools, yet and ZBrush don’t, makes me think alot.
wha ! just give me a stable release…all those crashes/freeze issues are killing all the fun (that using zbrush should/could be)
If they grow as a company and have a dev team just devoted to animation tools, than that would be cool. I could see them having a suite of products one day. But if they stay small than I agree they will hopefully stay focused on modeling and texturing.
