Really looking forward to the next SUGUK meeting. Eric Shrupps is over all the way from Texas and has a great talk planned on 'Developing High Performance Applications for Microsoft Office SharePoint Server 2007'. His company Binary Wave have a great product out called Sonar and I'm sure he'll pass on lots of great information he's learnt from building that.
Matt Groves is also going to be covering SharePoint Extranets. A topic lots of people want to know about as they look to get external third parties more involved with work processes. The part I'm most looking forward to seeing is ISA Server which helps with the whole publishing story.
