What m4/3 lens would you like to see Panasonic/Olympus come up with next?

A 9, 9.5 or (max) 10mm with very sharp corners, speed isn't very important (even 4.5 would do, if fully usable wide open). Small is a plus, but not at the cost of quality.

myybe a m4/3 version of the 4/3 12-60 (or 12-45, if it saves weight): I love my 12-60, slow focusing isn't a problem for most of what I do (and may be solved in future bodies), but it is still a beast of a lens...

Also,

A 75-300 or 100-300 with constant 4.0 and still very sharp at 300.
