I think it's been and gone! The GF1 would seem to have been their best (build quality) effort in this regard. It's a bit of a shame because going from a plastic to a metal shell allows for additional size reductions (See: Sony NEX5 and NEX3) and has the possibililty for some weather sealing. But with the GF2 (apparently) and the continued offerings from Olympus, I don't see a Leica-like or Fuji X100 type body on the horizon anytime soon. In addition to a lack of really high quality lenses (apart from maybe the 7-14mm Panasonic) it appears they do not intend aiming the products beyond the entry and mild enthusiast level.
