"Game changer" isn't the worst. It's not as bad as "paradigm shift".
It's a game changer when the paradigm shifts without a clutch.

Leaf shutters put some hefty constraints on how fast a lens can get. Copal, who have been the most common maker of leaf shutters only allow for f/2.2 lenses at the fastest.
Yet the humble Q01 manages f/1.9.

"The Tool That Will Shape Photography in 2013"

interesting...so 2013 was supposed to be the year leaf shutters took photography by storm. The first experimental Leaf shutters were made in 1911.

You can't use that lens on a 645D.

Why they introduce leaf shutter lenses now?
During the last year, they have issued three new 645 lenses, without it. I mean, what the .... ?!?!
This rumour smells fishy and makes no sense. Or Ricoh's strategy and planning is worse than what we believed.

Because pentax flash sync is only 1/180sec which is to slow for studio work.

No, it isn't too slow. 1/180th is more than fast enough to work with under controlled indoor studio lighting. It is when you go outdoors and want to diminish ambient light while using strobes to illuminate your subjects - that is when sync speeds of 1/180th limit your capabilities.

Ok, when I say studio I mean controlled light sources not native to location

+1
Although you still may need higher flash-synch speed in studio for hair or dress mouvements as well.

Nonetheless, if pentax want to achive serious digital MF market penetration they need to plug in their system quite a few jewels :
- Tilt-Shift
- Leaf-Shutter
- Fast =< f/2
- Fish-Eye
IMHO that's just commonsense.

Obviously very good news.
Let's hope they also will adress the need of really fast fixed lenses ; the P645 system desperately needs f/2 lenses - look at the new Leica S 100mm f/2 that was leaked a few days ago...

Why?

Depth of field is so thin at f2.8 on a medium format camera I don't see the point, especially in a leaf shutter lens which would be most useful with bright enviornments or studio flash work where you would stop down anyways?

That has more to do with the flash duration rather than sync speed.

Canikony supporters see the point because actually you may not get thinner depht of field with the P645 system than with any of their very fast f/1.2 and even f/1.4 primes.
Accessorily, "thin depth of field users" too
