Just saw this new SONY (larger than) four thirds camera.

Imagine a 23,4 x 15,6 mm Exmor chip. Must have a next-to-zero noise level...
And the E lens mount...
And the external mike...
And the active SteadyShot stabilizer...

Definitely gonna get a NEX-5 with 18-55 mm lens when they arrive here in june...
