Thinking About Developer Events: No Mix Conference in 2012 (via The Official Microsoft Blog)
As part of that reflection, we have decided to merge MIX, our spring web
conference for developers and designers, into our next major developer
conference, which we will host sometime in the coming year. I know a number of
folks were wondering about MIX, given the time of year, so we wanted to make
sure there’s no ambiguity, and be very clear… there will be no MIX 2012.
