I've thought about it. But in reality, there's no way I can convince the wife that I need to spend another $1200 on a camera that is marginally better than my E-M5. The faster focus is a plus for action shots, but I'd rather save the money on glass. To be honest, I've been fine with my E-M5 and have had no issues with action shots. I set mine in burst mode and usually get a few good shots of my daughter's karate tests. I'm not sure what extras the E-M1 will bring to the table for me...especially at another $1200 a pop.
