US market is probably the market that grows most rapidly for Sitecore. Large number of partners, solutions and developers. Developers, Solution Architects, etc - i.e. people - are the biggest values always. And Sitecore understands that!
I'm happy to see that Sitecore US will conduct large event for all Sitecore-related people - Sitecore Partner and Developer Conference Dreamcore - in Boston.
I'm sure all people will have fun :), but I'm also sure in wide knowledge and experience (and ideas as well) sharing. I won't be able to come myself, but this is what I expect personally - get new ideas and hear more feedback on implementations.
That is a great idea from Sitecore!
