I too would love to see a really fast prime for m4/3. And I really hope they can build lenses in more quality material. The cheap plastic feeling in the Olympus lenses (Panasonic lenses too?) really disappoints me.... Also the manual focusing wheel on the Oly lenses suck. But I have to say I compare all lenses to rangefinder lenses, so I am probably spoiled.
Maybe Voigtlander can make some m4/3 lenses in 2010?
