Unless people are going on 20 mile climbs with 7%+ sustained gradients, said people need to htfu. Might as well ride a motorized scooter if it hurts so much.

Just go with Campy Super-Record or their Chorus and 2010 Athena groups also provide 11-speeds at an affordable price. Or you can always go with the Shimano Dura-Ace Di2 (paddle shifters are reality!!!). And if you really need it, go with a triple chainring (which is dieing in the road bike industry) or just get a compact and live with it.

The only reason I asked that question is because Campagnolo came out with an 11 cassette this year, so I thought that Shimano would want to keep up with their main competitor.
I personally use a 9 speed cassette and I'm quite happy with it.

A 140 dropout spacing and 14 gears would be nice IMO... only one chainring, 50t with an 11-30.

hah... 140mm drop out with 14 gears... chainline anyone?
you don't compete against sexy with sexy, you compete against sexy with cute.
shimano has electric 10sp for offer.

Adds 5mm (0.2") to the cassette width, and you can center the single chainring. Since running the big-big is not an ussue now, and tests show that cross-chaining has no measurable effect on efficiency, I think it would work fine.

Your 20 speed probably has no more gear range than a lot of the old 10 speed (2x5) you just have more ability to find a gear that is your sweet spot in between... extra gears rarely give wider range, they fill the gaps.
I have a 10 speed with 52-39 and 14-34 freewheel. This gives me gear inches from about 31-100. A 53x11 is obviously higher, but I rarely use a gear over 100 gear inches.

) - about 91 inches. And before any smart asses jump in with the snark, I got 5th and won the field sprint, so I wasn't going all that slow (or all that fast, but more than fast enough).

I rarely even use a gear that high. The last sprint I did in a race couldn't have been in anything higher than a 52x15 (I was riding on my Old Technology bike ) - about 91 inches. And before any smart asses jump in with the snark, I got 5th and won the field sprint, so I wasn't going all that slow (or all that fast, but more than fast enough).

Don't descend much? Personally, I can't spin much over 80 rpm when descending due to the lack of resistance in the pedals, so I need a really big gear if I'm gonna keep the power on downhill. I routinely wish for something bigger than a 53/11 on descents that I'm trying to keep power numbers up. And I'm the opposite on climbs, I like to spin. I'm probably putting a 34/27 compact low gear on my next bike when I go on climbing races. If I had more gears, I could run a 53/39 with 11-30 or something, might need a longer RD for the chain wrap though.
By the way, you wouldn't need a longer derailer for that setup that you describe. You would just need to have a derailer able to clear a 30T cog. Most Shimano road derailers can (just) clear a cog that big.

Shimano is just in a mad dash to release as many successive increases in gear-count as possible, before someone figures out how to sexy-up planetary gears so roadies will want them. Once gears become infinitely variable, they will have to come up with some other scheme of forced obsolescence.
My guess? Chain links. More links/inch means a smoother stroke, with smaller gears on both sides to save weight!
