This is sort of a loaded question.
Mainly because the 1D-X or ANY camera no matter how much 1 person loves it will be good enough for everyone.
I for one don't need 14fps shooting or any of those features but i like the form factor, low light and the video capabilities.
Would i use the Ethernet connection.....NO, would i have preferred to see maybe a thunderbolt port added and headphone jack...YES.
It all comes down to the personal choice. You will either love it of hate it.
As for the marketing hype.... well thats marketing.
They will always need to make the camera look like the next big thing you need now, otherwise people will always be holding off for the next generation which will be bigger and better and faster etc, but eventually will never live up to expectations.
On saying all that, would i buy one and put up with the limitations it has for what i shoot, HELL YES!, because despite its limitations its still a freaking amazing piece of kit.
