Oly is finally shipping 45mm/1.8, and there is only a rumor [not Panny has only made an announcement] about Panny's 40mm pancake. But I'm torn between the two because I can't afford to have two short telephoto primes. So which would you choose and why, under the following assumptions (which I think are reasonable assumptions)? It looks like it will basically come down to which focal length and size (pancake vs. non-pancake). Both are comparable in sharpness and overall quality Panny will also be a very fast lens.
