I believe that Jeremy has said you can get an idea of the upcoming theme of LQ at
Android Questions. I imagine that re-theming a site as large and complex and with so many moving parts as LQ, while also keeping it running smoothly, is one heck of a task.
Personally, I like the current theme better than that one, but I don't come here for the theme--I come here for the content and the community. If Jeremy wants to change the theme, I say to him what I used to say to BBS sysops in olden days, when I was a young 'un: "It's your site. The final decision is up to you."
