I guess our software messed up and linked to our upcoming new design in an email. Oops! We actually showed it off at our booth at the Austin Game Conference with excellent response. It's really nothing more than a facelift to the interface. All the backend is the same, and for the forums in particular it's nothing more than a new theme. Might as well take a look at it and get used to it, as it's coming soon to a GameDev.net near you:http://www2.gamedev.net
And yes, we do plan to provide alternate and classic themes for those who just can't part with the 1990's dark, gothic theme. These alternates just won't be available for a little while longer.
In the meantime we will be keeping this current site as the www2 when the current www2 site becomes the current (www), so people who can't stand the change can view GDNet in its classic form.
