The future of road cycling
I am convinced that internally geared hubs are the future of all cycling disciplines. Granted, they're a bit heavier right now, but think of all the equipment they are replacing- cassette, rear and front derailleurs, double-chainring crankset, longer chain, etc. If someone came out with a sub-17 pound road bike with an internally geared hub that had the range of a traditional road bike, I would buy it in a heartbeat.
This is from a company that claims to have released the first internally-geared drop bar road bike.

You are correct.

That bike as is with a crank-based power meter would be a really good training bike.
Why are power meters $1K+? They seem simple enough. What is after power meters? First it was cadence, now power, next?
I'm going to sleep. Talk amongst yourselves.

Geared hubs will never be as efficient as sprocket systems, and will therefore, never be accepted by racers, and, by association, racer wannabes.
Unless they're used for downhilling or another event where wattage is less critical.

I'm thinking we'll all be 1KW power freaks in the future (with all the genetic nutra-pharmaceutical enhancements that will be available) and as such the 1 or 2% difference in efficiency between internally geared and chain drives will not be at issue. The issue will be drive train reliability when dealing with the power requirements.
(Hell, if I could afford it, I'd build a cross bike that'd have one of those internally geared 14speed rear hubs and I'd try and figure out how to get a double upfront....)

Electronic shifting, internal hub gearing, sub 12 lb bicycles, all by 2015.

What gearing would you get with an internal hub? Other than eliminating a front chain ring, rear dr. and some chain, what would be the advantage?

Less parts to clean.

Internal hubs would be easier to maintain because the external drivetrain would be a front chainring(s) and a chain. No external pulleys or cluster to get mucked up. Could be lighter and smoother shifting (electronic for sure) too. An internal mechanism rear hub could also include strain guages for a power meter.

i have felt this way for years. shimano nexis now has up to 8 gears. as far as chains go with an internal hub i think you will see the use a belt soon. trek recently introduced two belt driven bikes that they are selling as urban bikes. the district and the soho. my prediction is an internal hub version next year.
of course i don't see the component manufacturer's at all happy with things moving in this direction. less stuff for them to sell us.

Bike ≠ Car ≠ Ped.
Then there's the Rohloff with, what, 14 gears (can't remember offhand) and the widest, most evenly-spaced range of any internal hub.
The disadvantage that I see (besides the extra internal friction) is that you can't swap ratios like you can with chainrings and a cassette. You can change the front ring and rear cog as a sort of "final drive" to make the overall range taller or shorter, but you can't change the width of the range itself or the gaps between gears.

Let me guess. You're a masher, not a spinner, and you don't ride far, if you ride at all. Bikes with high handlebars and apparently simple internally-geared hubs appeal to people like that. But you know, given the enforced and almost universally-accepted over-complication of mankind's most elegant invention, you're probably right.
