There has been an update of mockup for future installement of Ubuntu (but not the immidiate next one), interestingly named Current theme rendition (3.2).

And a little word from the theme designing team to stop any unreasonable rumor, they want you to tell them what you think about this mockup, and so do I. Personally I could use a change from the default look of the current Ubuntu theme, while these not be right up the mark, but very close what I would like to see:

From the designing team:

I’ve just found out that several sites are promoting the rumor that this is the 8.04 theme, or are at least alluding to the idea that this is said theme in progress. I apologize for any confusion, and I’m sorry to say that this is may not be the next Ubuntu theme. It has been passed it up to the art team, and there’s a lot of work ahead for this theme.

If you are visiting and you do have ideas or suggestions, please post them here! There’s an entire sub-wiki just for your input! From “edible” to “post-eaten” the mixed reactions say this theme can be improved; a list of improvements are being gathered from various comments sections - but please post and encourage posting in the ideas section to make sure comments & suggestions aren’t skipped!
