I too think M4/3 has great potential. Sensor will keep getting better, and the cameras have a good compromise between portability and good handling. And the gear so far is very good. And I like that I can potentially use my wonderful Pana lenses on a Olympus body, if they come out with one I really like. I would love if the same was true of DSLRs, so I would not have two big lens collections, and not want to buy a Sony because I'd have to start a third.
