At least now I can make my decision without the looming possibility that Pentax will themselves introduce something which would serve as a compact "street-shooter."

Look at it this way. You buy the Oly and if Pentax ever comes up with a street shooter you can sell the Oly for maybe a $200 loss. Think of it as a rental for the 2 years minimum it's going to take Pentax to come up with what you want.
