The Olympus OM-D certainly seems an interesting camera. I am not 100% certain that I like the faux SLR styling from a practical point but it certainly ticks a number of boxes for me. A mix of controls not unlike a film camera with more modern stuff on the back, a fold out OLED display - similar to the one on the E-P3 (which is outstandingly good), an integrated EVF, a tough alloy body and a weather sealed body to go with the lenses.

Pity I won't be flush with cash.
The other thing of interest would be the Olympus 75mm f/1.8 which would go nicely with my E-P3. That would give me a fast 150mm equivalent lens with autofocus which would be ideal for one of the jobs I have up my sleeve.
Guess I better start saving.
