Gigabit ethernet, yes. Standard 10/100 ethernet, no. Problem too is that tethered shooting is currently developed aaround ports other than ethernet. Of course any networking built into a device brings with it the prospect of hacking prevention and security needs. I can imagine the complaints. Still, networking in a pro camera has its legit uses.
Buttons have moved around on the back of the D4. The AE-L/AF-L button is MIA. Pros (and many of the rest of us) don't want to have to get used to a new UI/UE and functionality. We want a smooth transition to successive models. At these prices, Nikon - and Canon too, make no mistake about it - should be babying their pro customers, not imposing needless learning curves for previously perfectly familiar, important functions. Missing AE-L/AF-L button indeed.
EDITED/ADDED: Meh(!) again. I checked the detailed spec at imaging.nikon.com. The wired ethernet port is IEEE802.3u standard (100BASE-TX). Slower than USB 2.0 hi-speed. Why not Gigabit ethernet!?! My guess is a dumb cost/licensing decision; certainly nothing to do with forward or backward network compatibility. Gigabit ethernet is solid.
Also, there's no speed/class spec for the optional new wireless WT-5 transmitter. So I suspect 802.11a/b/g, in the absence of any spec-brag about 802.11n. Slow again, despite the fact that 'n' is cheap and fast and the IEEE 'n' spec has been final for quite a while. If I'm correct, it's just a false economy that D4 owners will have to live with.
