It's not like you need permission from WotC to create your own races. All you need is pen & paper.
But yes, it would be nice to have a book like Unearthed Arcana later that gives guidance on making your own races and classes.
For the 5E DDI (or whatever the online rules database is called) it would be awesome to have a function to publish, share and rate homebrew content. That way, if I want flumphs as PC race, I can check the homebrew section whether somebody already made one, and then enable it for my campaign with a click.
