Prototype of the 16-80mm:

The size seems quite compact for an f4 lens of that range.
Hopefully the final lens will feature the same form factor.

This doesn't really look like a "prototype" lens anymore. 
I suspect the reason for the delay is more about production capacity - which may relate to this news:

Depends on the hand. The already available 16-80s from CaNikon are about the same size. But given the shorter lens-sensor distance, the whole unit will appear very compact, yes.

And hopefully the final one won't have the misaligned zoom ring either.

I wouldn't really switch to Fuji X-System for those lenses. Almost any system has good alternatives in those focal lengths and most are even cheaper/smaller/better.

For me it would mean changing the body and most of the lenses anyway by going back to APS-C, so it's not like I wouldn't have been losing a lot either way.

That 16/2.8 WR - I don't get it: It's not much smaller than the really great 16/1.4 and two stops slower. Faster AF? Weather resistance - and again water damage excluded in warranty? The WR lenses mostly are sharp and relying on distortion correction.I wonder if that's what people wanted?

So it's not a pancake like the Sony / Samsung lenses with the same stats? Odd.

Looking at the pictures, it's more like a stack of pancakes...

It seems to me that there is unreasonable excitement about mirrorless lenses lately. Size, weight, price are far from what was predicted. The engineers do nail the objectives here and there but overall that is not the case. We've seen it with Fuji Sony and now Oly.

To be fair, DSLR lenses are getting bigger and heavier too.

Yes, the f/1.4 ones but f/2.8? On a mirrorless? The 50 and 35 mm both are f/2 and a filter thread for M43. This 16/2.8 comes with M49 and is a full stop slower.
