I'm not really sure why everyone is hung up on what other cameras sold for when they were first announced.
The only thing I compare it to or care about is what is available and on the market TODAY as far as competition and what is that price TODAY.
So, for example a 5D mark II is about 2,100 new ebay or 2,400 new retail right now.
That is really what the mark III will need to compete with or show that it can outshine the mark II by $1,100 to $1,400
Forget what the yen is out now or was at 3 years ago, can the mark III be a viable product in the US now at a $3,500 price point?
In the case of the new ebay mark II it is a 66% increase.
Kind of the same as buying a new car, I go down and see what is new on the lot already (last years model) and when they announce the new 2012 is X price is it really worth spending that much more for the other new one sitting right next to it. If it has a bunch of upgrades then it's worth it possibly, but I really don't ask how much the one on the lot was priced at when it came out.
It's interesting to me that most things that are technical in nature like computers, monitors, etc... tend to get better every year and the price drops every year for the same features. I don't really understand why cameras don't fall in that realm, it's a shame isn't it?
