Everyone needs to understand the difference between LIST and STREET prices. The Canon 5D Mark II when released listed for US$2799, however (rebates/sales excluded) usually streets for about US$2499 (body only). Average price range for the 5D II can be anywhere from $2000 to as high as $4000 with an extended kit, factoring in rebates and sales.
Adjusting the original 2008 list price of $2799 for inflation through now in 2012, the list price would land squarely at $3000 adjusted. So the difference is not really $1500 for better AF and an extra megapixel (and probably a vastly improved sensor like the 1D X's)...the difference when you adjust for inflation is about $500...which is FAR, FAR more reasonable if you ask me, and certainly easier to swallow than a $6800 price tag for the 1D X.
I'm really quite bummed about the CF/SD bit...I'd much prefer two CF slots, or perhaps a CF slot and an XQD or something capable of SDXC speeds.
