I have been there for the last 2 years, and I was able to pre-register this year. I go for the talks and the awesome energy that the event irradiates. I am pretty sure the quality of the talks and the energy will be just better than last year.

Developers like conferences and free gadgets, yea there might be some people looking to get some "free" $500 gadgets, but I don't think that will ruin my experience of awesome tech stuff and meeting the teams from all the different technologies that work on stuff I use every day.
