There have been some new rumors about the competition during the last 24 hours. Before that I can tell you that other soruces confirmed the Panasonic and Olympus announcement dates. June 13 for Pana and June 30 for Oly. So be prepared to follow the announcement live on 43rumors on those days!
The real suprise is that Canon seems to have no plan to make a mirrorless system at all! Anyway, I hope Olympus and Panasonic do recognize that they are not alone anymore. It’s time for them to bring some real r-evolution!
