The session from San Diego is at https://www.ciscolive.com/online/connect/sessionDetail.ww?SESSION_ID=83806&backBtn=true Doesn't look like they've finalized the slides and video for that session yet though. In Milan they deployed 325 APs across 6 controllers (3 HA pairs). From experience at the US Live events, there's 10-15K people in the main hall during keynotes, there's probably close to 100 APs in that room alone with the stadium antennas for the density needed. There's a LOT of people trying to tweet during and this year periscope the keynote speeches. If people are interested, I know a couple of the Cisco folks tend to lurk on this and other lists and can probably provide more details if asked nicely.
