hmm boardman hybrid replace the flat bars with drops and this was done 4-5 years ago,
except it's a completely different bike.
Specialized just showed their first: [url= http://www.bikerumor.com/2012/07/10/2013-specialized-road-cyclocross-womens-commuter-bikes-roubaix-disc/ ]Roubaix Disk[/url]
I suppose there will be loads announced for the 2013 bike.
Unfortunately I have a newish Cervelo RS, but I am not sure how long I will be able to hold out on a nice disk bike.
Having said the above I am strangely liking/wanting, but just had a new quintanaroo so going to be really hard to justify to the SO
I'm crossing my fingers that there'll be a huge overstock of mechanical DA9000 once everyone decides they need a Di2 Disk groupset. I can't see shimano holding out much longer and risking letting formula into the market as a 4th groupset provider when they're already competing with SRAM.
Campag - if your bikes italian
SRAM - if you want lightweight, hence no electric stuff
Shimano - everyone else.
ABCDEF? - if you want disk brakes
So it's Shimano that stands to lose most by another compettitor gains market share.
The only concern I'd have is about a big crash with lots of riders and a rider landing on the red hot disc of someone else's bike
Big pile ups are extremely rare where people are doing a lot of braking (ie on big downhills).
That said, I have no problems with the rim brakes on my road bike (unlike the the discs on my mountain bike that have been known to over heat).
I don't use carbon rims though.

Certianly going to make quick wheel changes in the event of a crevaison interesting...
Why so? No need to loosen/undo brakes to get wheel through them. So, faster and easier, surely?
Plus will be able to continue riding with a bigger buckle than rim brakes can tolerate so possibly less changing of wheels.
CFH - guiding discs into calipers.
The UCI are enforcing the rule that the lawyers tabs on forks have to stay on from after the TdF. And a properly designed road calliper with guides will make everything easier, unlike mtb callipers where it is so easy to get the disk caught on the pad.
mods - two month ban for CFH for starting this thread......

Are the UCI enforcing Lawyer tabs, or are they enforcing the no modifications rule? Big difference, first tabs exist, the later well bikes will start appearing without tabs.

What makes you think they'll do it on road bikes, when they have so far failed to get it right on MTBs? Not saying they won't, i just don't think they will.
As for why? marketing, most of the time disc brakes are pointless on a road bike, currently riding round on 5 year old Open pros, c25000miles, for reference i wore out a set of 217sunsets in 9 months.
how thin can you make a rim, and how narrow a tyre could you run ? would you want to and would it be beneficial ?
They can't use bikes that are not approved, and meet all safety standards. And they can't modify the bikes at all, so that means they will be riding with lawyers tabs.
and meet all safety standards.
what safety standard enforces lawyer tabs? I know US companies started to use them to prevent legal cases but is there actually anything saying they have to be used. Pace forks never used these tabs, or at least weren't long after the date everyone else started to use them.

tyre width isn't going anywhere IMO, 23-25 seems to be the sweet spot. Which also determines how wide the rim can be, both max and min.
as for rim thickness, you can't get much thinner, you need to hold 150psi without the rim failing or the tyre coming off. What you can do is partially remove the sidewalls, just have to watch the internal design so you can still moutn a tyre.
