To answer your question, I have had to wet clean my D4 once in 8 months. And right from the get-go in 2007 the D3 had the reputation of being a dust magnet requiring constant vigilance.
FX sensors are 2.25 times the area of DX so one stands to accumulate 2.25 the amount of dust. I support the OP in indicating one has to develop the cleaning skills and that yes it comes with the territory of being a serious digital photographer.
As an aside the D4 is a phenomenal camera for what you describe: killer AF, handles low light like a dream, and fps and buffer make it a great speed cam.
