The dates are now locked in: December 7th - December 9th.
We've had one "pre-Summit" meeting with CCP and a couple more on the horizon. While I expect this summit will be much different in tone to the others, things looks promising overall. There will be no Kool-Aid drinking on the CSM, but we've been encouraged by what we've seen recently. The tone of day to day chats with CCP is unrecognizable compared with just a couple months ago. The numerous written dev blogs and video blogs should keep coming right up until Crucible's release.
One thing we want to make sure of is that we get what information we can about the Summit into your hands as soon as possible. As the Summit gets closer, we will make sure to re-post links to blogs, twitter accounts, etc... so you can follow the non-NDA stuff in real time (more or less). We're also hoping to get a much quicker turn around this time on the official summit minutes, holidays permitting.
Feel free to suggest stuff for us to ask about / discuss here and we'll post more in terms of official details / agenda as soon as we can.
