Is it time take Micro Four Thirds more seriously?

I had the chance to play with a Panasonic GH2 yesterday. I tried out a bunch of different lenses and the Lumix 20mm f/1.7 was a particular favourite. The point, though, is that I was struck by just how good this gear is. I'm starting to wonder if it wouldn't be a smart move to leave the 5Dmk2 and the L lenses at home and start buying into the Micro Four Thirds system. 

Those lenses fit on a bunch of cameras and they're small and light. I could carry a camera bag 1/3 the size of my 5D bag that contains a camera, a couple of zoom lenses and still have room for a whole bunch of primes. Right now my bag usually contains a camera, a 24-70mm and a 70-200mm. I usually carry at least one prime, either a 50mm or 100mm macro lens but I'd love to carry more (like an 85mm if I could afford it).

The only thing holding me back has been my perception that these Micro Four Thirds lenses can't be as good as my big L glass and, honestly, they're probably not. Not quite. But if I can carry a good selection of prime lenses in place of my single 24-70 f/2.8 L, well that's kinda tempting. Plus, of course, they're a lot cheaper so as well as the weight saving there's a cost saving too. 

The only point against doing this is how it would look to clients. I don't think they'd be too impressed to see me arrive with what seems to be much the same as their camera. 

I'm not placing any orders just yet but I have to admit.. I'm considering it. The shot above was just one of my snapshots while I was playing around with these lenses. It's a picture of my very old, very grumpy Devon Rex cat Elliott and it was shot with the GH2 using the Lumix 20mm f/1.7.
