I think the next iteration of Cannondales (and probably a few other companies) will be disc only. I'm really leaning towards the new Cannondale Aero bike and unless the brakes are near the bottom bracket its going to be disc only.
I wish I could just fully convert and sell off my wheels while they still have value, but I can't really afford to replace my TT bike as well. Luckily I just have HED Jet 4's and Flo 60's, so its not like I have thousands invested.
