No. It may be three more cords.
... assuming Apple doesn't do something clever. Considering Apple was clever enough to come up with ADC in the first place, I'd be surprised if they didn't achieve similar results whilst ditching the proprietary ADC connector.
People have already speculated how this could be done. Using one extra 'combo' cable to connect to the screen, with firewire and USB connectors breaking out at the other end is a possibility. Heck, it could even be possible to bundle power into that as well.
This might have a couple of advantages. I don't own a current ADC-capable display, but I'd imagine that for those who need it, getting a proprietary ADC extension cable for positioning the screen far from the Mac could well be difficult and/or expensive. At any rate, Apple would be the only supplier. With Bluetooth keyboards and mice, it's not beyond belief that people might want more freedom in relocating the screen. With a 'combo' cable as described above, users are free to extend whichever connectors they use as far as they need using standard off-the-shelf USB or Firewire extension cables.
Secondly, dropping ADC could lead to a quicker supply of leading-edge Mac-compatible graphics cards from the major vendors. A whole new variant of the card with an ADC connector as well as DVI would no longer be needed.
Overall, I'd suggest waiting to see what Apple come up with before furrowing our brows
