On the Symfony blog today they've announced the first set of speakers for this year's SymfonyLive Portland (2013):

Great news, we’ve selected the first speakers for Symfony Live Portland! We received a lot of great talks proposals (around 150, how amazing!) and we had a real, real hard time choosing between all of them.

Their list of speakers for this year's event will include:

• Michael Dowling
• Jeremy Lindblom
• Benjamin Eberlei
• Taylor Otwell
• David Zuelke
• Anthony Ferrara

There'll also be workshop session (one and two day) as well as time set aside for lightening talks. You can pick up your tickets here or just find out more information about the event from the main conference site.
