Are pancake primes extinct ?

I have nothing against corrections if they are required and useful - I have the 20mm and it's a great lens. I do wish for a longer, portrait-oriented lens a la Pentax 40mm - I dangle my camera around my neck a lot and I like the combination (E-PL3 + 20mm + etc.) to remain vertical. An equivalent of the 40mm (35mm pancake lens for m43), even F3.5, would be my next buy, but size is important and even moreso is the balance of the ensemble. In this respect a similar Pentax arrangement is larger overall but stays better in place...
