The guys I talked to were still using friction shifting. It may be their personal preference. I see that all the new bikes come with indexed shifters and that some of them are no longer switchable.
That Di2 stuff has got to be the cat's meow for a tri or TT bike. Anything that lets them stay better in aero position has to be a good thing.
