Given the respectable advances, what's been left off of the rig, isn't insurmountable.
They can cry all they want about the fact that Lexar and SanDisk are staying on the sidelines, but that is the future, much as 9 pin fire-wire was to 6 pin.
Wireless, that's where the D4 is positioned, and as yet, Canon has never had the best imagery to date, video being the exception despite the marketing speak but uncompressed 4.2.2, well, and that's pretty darned snappy, no matter what Canon does.
And more than once, I've been in my local retailer as Canon people come in to buy Nikon glass.
Fine to whine, but I'm already in line for the D4 and D800...time will tell.
