- 23mm f2 with extra software correction to allow for tiny size (the 23mm f1.4 looks rather large and I'm sure will be optically excellent).
- 35mm or 40mm f.95 super speed flagship as Denizg7 said.
- 16mm f4.5 that is tiny and optically perfect at all apertures, with special micr0-contrast and flare control. The ultimate wide/street lens.
- 18-35mm f2 zoom. Should be small, razor sharp, and covers the equivalent focal lengths of 28mm - 50mm at f2. The world needs more small/fast/limited range zooms.
