It's not been discussed if the new lenses are designed for the 30% crop factor i.e. Is the 45 really a 59mm? If you shoot wide this might present an issue it would for me. Even the 30mm would not be that wide if not designed around the crop factor.
I know many don't care about this but just curious.

If not the focal length is the real (approximate) focal length then it would be the first(?) time a manufacturer doesn't provide the real focal length, small compacts excepted.
Assume we like 4:3 format so we cut down 135 36x24 to 32x24, then the crop factor compared to 44x33 becomes 55/40=1.375 (otherwise it's 1.27)
So the 45 is then 33mm 135 equivalent, the 90 is 66mm, and the upcoming 30mm is 22mm. It's a suitably wide widest angle I think, sure it's not enough for some architecture and some landscape, but the camera is supposed to focus on lightweight so it's a good trade-off.
