Panasonic today announced the much anticipated Leica 25mm f/1.4 Summilux for Micro 4/3:
Unlike the regular (non-Micro) 4/3 version, the new lens is fairly compact and light (~200 gm).
Availability is expected August 2011, and pricing has not yet been determined.

Meanwhile, Quesabesde (translation) is reporting that Panasonic revealed that there will be two additional lenses announced this fall. At the time that Panasonic first revealed the development of a 25mm f/1.4 lens, they also revealed that a "bright [standard] zoom" and "bright wide angle [prime]" were "under consideration". It therefore seems likely that the upcoming lenses will fall into those categories.
