Define "not too expensive" ...
I don't make any money from photography, so can't justify high spending that way.
Anything over $1,500 would normally make me pause, and I know this thing will be more than that.
Plus there is the cost of new lenses. I have three AF FX primes (20, 35 and 50 1.4) and I don't know if they will shape up to such high resolution. So I will probably have to buy a couple of zooms.
My feeling now is that if the total cost is less than $5,000 and I can see this camera lasting me for at least 5 years, I'll go for it.
But I know that I will be easily swayed once it is out.
After all, the worlds economy is about to go down the plug-hole so who needs money?
