We've known for a long time that Ubuntu Budgie is an official new flavor. And since then it seems that the entire team and community have turned to developing a version that lives up to the official flavor of Ubuntu.
Although the first alpha has been omitted, developers are still working on Ubuntu 17.04 and the Ubuntu Budgie team is no exception. Like the rest of flavors, the Community created around the new official flavor you are looking for an official logo and a wallpaper, elements that every distribution has.
The process is not easy since they want to have the entire Community, and they have also been slow to launch the vote since there was no graphic developer who could create a sample. After having found it, users already have available the samples to choose the official logo as well as the first Ubuntu Budgie wallpaper as the official flavor.
Ubuntu Budgie 17.04 will release Budgie version as well as a new logo and an official wallpaper
And if everything goes as planned, next January 26 we will have an official development version of this new flavor, a version in which we will already be able to see the new logo as well as the wallpaper, or at least that is expected.
Although personally I think that the most striking or desired by all users will be to see what new Budgie desktop will bring as well as the official flavor. A few days after the flavor was made official, the Budgie Desktop developers claimed to be in contact with the flavor developers to incorporate all the new features of the desktop to the Ubuntu Budgie versions. This means that Ubuntu Budgie 17.04 will have the new version of Budgie Desktop, something that many desktop users are waiting for and of which we still have nothing concrete.
