The feature I have been missing in E-P2 is phase detect, since contrast detect makes focussing with manual lenses slow and much more difficult. A decent phase detect allows focus confirmation with sound or led. I believe that the next update will bring phase detect to Olympus EP series. Fuji has developed a module which allows both contrast and phase detect for compact camera, and Sony´s Alpha A33 and A55 have EVF with phase detect. Sony uses a translucent mirror in its system, so I don't know if it uses the same system as Fuji. Anyway, since the camera makers cross-licence their technologies, I think it is likely that phase detect is on its way to Olympus as well.
