Looking at the lens map, I think there will be 35mm f1.4/50mm f1.4/85mm f1.4 (all DFA * primes) and a 20-ish mm lens that probably will be f2 or f2.8 and a little smaller size.
This is the lens map:
http://www.ricoh-imaging.co.jp/japan/products/lens/images/K_Mount_Lens.pdf It shows a line around 20mm with the title "ultra wide-angle single focus lens" and the one around 30mm says "large aperture wide angle single focus lens." Obviously at this point the actual focal lengths aren't certain.
