gnome-shell future plans?

[kaddy080 gmail com]

Hi All

is there an official blueprint of what gnome-shell will look like when released? I seen a mockup a while ago 
that was a bit like unity (but wayyyyy better)   is that official? any links to official mockups/designs being implemented in the future? or will it look like what it does at present? :s any planned features for implementation that we 
can read about? can't find much......

cheers
