I just learned that in some regions the E-M1 announcement will happen at 5am London time and in some other regions at 6am. This means that at 5am London time first official E-M1 info and review will be published here on 43rumors. Converted in other timezones this means:
9pm in Los Angeles
12am in New York
5am in London
6am in Berlin
13:00 (1pm) in Tokyo
As usual stay tuned on 43rumors by that hour. I will keep you updated with links to reviews, image samples and preorders.
