Don't go near the internet much then!
Firstly the 1DX was delayed for many months, and when it did go on sale there was a problem whereby if you used the Spot Meter in low light (I think) the camera froze.

It is hopefully fixed with the latest firmware update.
Some D4/D800 cameras were freezing up, there was also a green cast on the LCDs. Although Nikon said it was not a problem, but a more accurate LCD.
And just to complete the set, with the 5DIII, the metering can be affected by the LCD being on, light leaking into the metering sensors, in very dark circumstances. :shrug:
Lots of people are making lots of lovely pictures with those cameras though.
