I am 100% behind shelving the universal design talk until either you guys get a developer on that can thoughtfully comment on it, or GDC. I would love for you to have some people like Dyack or Molyneux. Some of my favorite podcasts have featured developers- especially the one with the guy from FASA!!
PS- I was a huge fan of Operation Flashpoint 2! That game needed some more polishing, but there were more interesting things tried by that team than in either CiD:BO or Medal of Honor!
