Agreed Geoff,
4/3s are full frame four-thirds, aren't they, so long as you use the 
lenses that go with them.
Else, 35mm are also part-frames compared to 6 x 6 (120) or larger formats.
It's semantics ok, but isn't everything a question of point of view?

More primes: I agree with this to the full.
Have a nice day
