The E3 floor plan has been revealed in case anyone wanted to see where everything will be. Unfortunately the little booth are unreadable in these images (the images needed to be about 2200+ pixels across for those to be readable ) so I've included links back to the original pdfs for anyone who wants to read those. The meeting room area was also totally unreadable so unfortunately the pdf is the only option for that.
