Considering updating my old EP1 at this point. I have a slew of lenses, love the body, but ready for something new. I've heard murmurings of "pro" bodies coming out, but I don't really know what that even means in the m43 sense. The GX1 is a gorgeous build -- as is the OMD -- but theses already seem to be dropping in price. Any thoughts on whether I should stick it out a few months for something really nice from Oly or Pany? Money isn't the big issue. Thanks!
