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

As long as it's a prime, it's weather sealed, and it's noticeably faster and sharper than any of the "meh" tele zooms available now. And as long as it isn't more than $1500 or so, depending on the speed of course. I have a feeling that going much faster than 5.6 would just make for another $5000 beast that is just too far out of reach.
