That 16mm f2.4 would have been interesting as well...
I know they publish all of the options partially as a way to obscure their real plans, but it would sometimes be cool if they went and did a couple...
And what really drives the final answer? Is it all anticipated marketing (a larger market for a 21mm than a 16mm), or do they go and build prototypes and say "ah, the 16mm is cool, but the mechanics and assembly would cost double what the 21mm will cost, so we'll do that one instead..."
Ah, well... I'm still many pennies away from saving for the 21
