For the flats and rolling hills I will use a 50-42-32 front chainring setup for a close and even spread of gears, at 44 I can no longer push a 53/12 for any great length of time so I don't even bother to try any more, and a 32/21 is plenty low enough for this purpose.
For bigger hills I will use a 53-39-30 front chainring setup (53 for the downhills only), as a 30/21 is approximately equal to a 39/27-28. If I need anything lower geared than this (which I seldom do) I will then put on an 12-23 rear cogset, as a 30-23 is approximately equal to a 39/30.
Therefore, I really see no practicle need for more cogs in the rear, which necessitates greater wheel dish, or weaker setups in general, 9 or 10 is enough. And, using my setup the gearing is already very closely spaced anyway. I use a bar-end shifter for the front derailier since I have never felt comfortable with Ergopower or Dual Control front shifters, it's just a personal preference.
What I would like to see is a setup that uses the same 9-10 speed cogset but with less wheel dish. In other words, more refinement of the existing setups available.
But, marketing is what it is, and companies need new toys in order to get us to part with our hard earned cash, so I would forsee more changes and new designs. Not so bad for us technogeeks anyway! Even for a retroactive geek like myself. I don't mind new technology, just as long as it solves an existing problem.
