It would be great if MS was planning something special hardware wise for TechEd, but I highly doubt they are going to hand out 10,000 RT's, or Phones. Operations and architecture people just don't seem to demand the same level of lust from MS as the developers do.
We even see it with the software announcements. MS isn't even going to talk Windows 8.1 at TechEd, they are saving it for a week later at Build. I am going to be interested if we even get to hear about 2012 R2 or if that will be saved for the Euro's instead.
