half an inch shorter and 145g lighter is a considerable difference.

I'm interested in lens, but the speculation about the pricing has me a bit put off.

I don't understand those primes at all. Isn't half the point of a wide angle prime to have a fast aperture?

I guess most of these will be used on things like the C300 video camera as opposed to the DSLRs though.
