Canon HG20

I want to see real upgrades! things like:
- 1080p @ 60fps for keeping up with sport and good slow-mo's
- bigger sensors for better low light shooting
- larger optical zooms, i mean is 12x really the best they can do?
- reducing prices, the people with money have bought their HD cameras by now, now lets allow the rest of us bask in the HD goodness! (Following Samsungs lead)

50p and 60p formats are only available in AVCHD when shooting 720p, not 1080p. So we would only see 1080/50p or 1080/60p with a new camcorder format.
Bigger sensors are available - look at the Samsung VP-HMX20. However, the latest Canons have amazing low light performance from their existing sensors, as do the top JVCs and Sonys.
Optical zoom is a matter of size. A bigger sensor requires a physically larger camcorder to get the same zoom factor. This is why cheap consumer camcorders with 1/6in sensors have 20x or even 35x optical zoom, whereas the HD ones with bigger sensors max out at 10x or 12x. Size is such an important sales point I doubt we will see camcorders getting bigger just so we can have larger optical zooms.
Samsung is reducing prices - hunt around and you can find the VP-HMX20 for as little as £425. Canon's HF100 has fallen in price a lot too recently.

I agree with James that the format dictates the possibles. Can't have one's cake and eat it.

Greater zoom can be had via say a 2x converter which can be had reasonably cheaply; obviously too you can add a wide converter. Raynox make some very affordable converters which are optically very good. I have a Raynox 250 (£45 normally but I paid £8 on Amazon :) and a Raynox wide converter (£23). The Raynox 250 also fits my Pentax 16-45, etc, on my super cool Samsung GX20. I'd like to add too, since it does not figure much in camcorder talk, that the Canon lenses on my HR10 and HG20 are very good lenses.
