Bringing the best software speakers to the East of England
Personally I feel Continuous Deployment would be a nice follow on from all the Agile talks. Software craftmanship is also a great idea.
As for the business topics, I'd like to see the low-budget start-up and both 10 things...
A good topic would be a review of the various open source automated testing tools (pros, cons, experiences). A general topic on testing would be good as agile teams approach testing totally different to traditional waterfall teams i.e. they leave the testing to a designated BA/Tester. How can all the team members (BAs, Developers, Testers) contribute to testing?
it would be good to see something on BDD and specification by example, for me this is the key which ties agile development together end to end
