Which Micro System Camera Is For Me?

I'm downgrading from my Canon 50D to something more small and easy to carry around.

I want something that will take clear 4x6 to 8x10 shots.
Preferably 12MP or higher.
A viewfinder and interchangeable lens are a must.
And it must also shoot RAW images.

I want something that has minimal noise.

I have looked at 3 different cameras and have come close to buying each one at a point but didn't.

These were most recent to least:
Panasonic Lumix DMC-GX1 (Dislikes: No viewfinder and has a touchscreen)
Olympus PEN E-PM1 (Dislikes: No viewfinder and sample photos were too noisy)
Nikon 1 J1 (Dislikes: No viewfinder and too small of MP)

The Panasonic is the one I'm leaning most towards but I'd like to know if anyone knows of a comparable camera with a viewfinder? I don't want to spend an additional $100 or more for some EVF.

My price limit is $900.

The Nikon has a viewfinder.

For just a little more you can have one of them. Http://www.nikonusa.com/Nikon-Products/Product/Nikon1/V27504/Nikon-1-V1.html

On pixel counts.
