Olympus PEN E-PL1

Olympus has released a new Micro Four Thirds camera, it's slightly smaller and cheaper than the E-P1.
It could be interesting with the Panasonic supercompact lens 20mm F:1.7, adding the missing image stabilization to the latter, and being more compact yet than the Panasonic GF1, though maybe not a lot in practice.
Here's a practical round-up page for the camera.
