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

If Oly makes a 25mm 1.4 prime that is metal and snap focus while focusing on optical perfection over size you will have a winner.  Those who would want a bright fast lens don't care about size too much.   There are already decent smaller lenses around that fov but not a metal water resistant one that is pro grade.  The Panny 25 is great but Oly needs to blow that out of the water and give a reason to use this lens body combo for serious use.  Just keep it under $1,500 please.  Also make it in silver only to feed the trolls
