I am at a loss to understand why some are so infatuated with the Lithium-Ion technology when that means batteries that age rapidly whether or not they are used. True, Li-Ion has a slower discharge rate, but this is offset by the fast ageing. With Lithium-Ion one needs an uninterrupted battery supply; with Ni-MH spare batteries can be stored for a long time.
http://en.wikipedia.org/wiki/Lithium_ion
"A unique drawback that we can see to the Li-ion battery is that its life cycle is dependent upon aging from time of manufacturing (shelf life) regardless if it was charged or not and not on the number of charge/discharge cycles. This drawback is not widely publicized."
Also, live preview is far from an advantage. It would mean a sensor and color filters constantly exposed to light, which would shorten the life span of these light-sensitive components. It is also a complete waste of energy, since the sensor acting as a video camera would incur more use of precious battery power. Nor anything ever replace a proper optical finder.
Bogatyr, we live in a world of technological progress. Whether or not you like Li Ion will be the future for awhile at least. Nikon already uses it in the D2H,X and I don't see them compalining too much. I could care less really, but I'm a realist and I fully expect any new Canon's to also uses it. It's already in the consumer range, so what's the big deal.
As for the bigger LCD, not being needed, well I totally disagree. In fact you seem to be arguing for arguments sake. If you think a 1kg camera is an ultra lightweight device, you been smoking something strange. I get the impression you don't like or are scared by change. I wouldn't be buying a digital camera then, because you better get used to it
Like you and, I take it, all photographers, I love technological advancements insofar as it increases our photographic possibilities.
That is why I ask for - precisely technological progress. In very many instances, inferior solutions are used because consumers could not care less about dependability, durability, longevity. Nor is the possibility to be excluded that some lithium technology may give us batteries that can be stored for a decade or more, and be capable of many more charge/discharge cycles than present solutions. It may or may not be lithium-based, but the point is that it should be done. Technological progress should not mean the introduction of tools with vastly inferior service life and recuced dependability. Thus, progress should involve a striving towards making new products - at least the high end versions - long-term dependable.
However, this will only happen if the market demands it. If "everyone" - that is a large majority - is satisfied with what functions in the moment with no thoughts to long-term dependability, many of us will be sorry later when our equipment fails and there are no spare parts, no new batteries, and the old have ended their way too short service life. The answer? Of course, that can only be more technological progress, with more development efforts devoted to the construction of things that last.
As for the weight of camera bodies, I fail to see how a call for hi-tech composite bodies can be labelled "resistance to change." Change is a prerequisite to the creation of better constructions. Moreover, the smallest and lightest possible camera body is no advantage in real shooting situations. Consumer class bodies are very light, but try to hand hold these at shutter speeds of 1/16 of a second. It is possible with bodies like the 1D II, which I have used with a 1.4 lens in almost complete darkness with ISO 3200. I assure you, the same stability would have been close to impossible to achieve with a lightweight consumer class body. So, the ideal weight of a camera body very probably lies somewhere between the consumer class and the 1D-series.
In my humble opinion, change should always be change for the /better/. Perhaps it would be wise to be quality and performance conscious, and demand that kind of change?

) it's suppose to be full frame with 12mp. It's not suppose to replace any of existing camera but it is suppose to fit between 1d and 20d. But let's wait for another week or two and it will be clear.
