>Nikon updates are always cumulative. It is the entire application every time.
Look at the properties of the file on your computer. You'll see the files get slightly larger with each upgrade. (Though I keep only the latest firmware version on a CF card in my camera bag, I keep the old firmware in a folder on the computer, Just In Case...)

Here's the quote from Nikon.
How do I update my camera firmware?
This is the D4 A:1.04 / B:1.02 firmware upgrade download - Please review the information provided, and click the appropriate download at the bottom of the page. All firmware upgrades include all previous firmware upgrades.
I am a happy camper with the new firmware, it has improved the focusing system greatly. I photograph eagles on the Mississippi river and have always had trouble when the bird would dive toward the river and would be against a backdrop of black trees. If I lost focus my D4 would not reacquire focus until the bird was closer to the water.
This past week that problem disappeared, my D4 would reacquire focus without a problem against those black trees. I was using my D4, a 600 with a 1.4 tc.
That's good to read. I was photographing bison a few weeks back with my 600mm along side of the highway when a few transport trucks came down the road. I tracked them on AF-C / S, head on, and all were out of focus. I hope Nikon gets their act together with the D4 cause I am loosing patience with them.
I can see why Andy Rouse has ditched his D4 and gone back to Canon.
Don't get too impatient, I ditched two Canon 1DMarkIIIs because of the focusing issues and it cost too much money to do so. I don't regret that decision because I love my D3s and D4. All cameras have issues and I just figured out a few work arounds that were successful.
