This IS coming this month. I've been feverishly working on it this week (sorry, I've been really busy! Too many friends getting married this month!) -- I plan on having it available for download prior to the season opener tomorrow night. I'll release it in a few different resolutions, then lean on you guys a bit for some resolution requests.
Just so you know: The native size of the wallpaper is 2560x1440 -- it'll be plenty big to start!
