Not gonna happen w/ this D700 owner.
3x more memory cards needed.
3x more HDD space needed- you shoot 44 weddings and tell me this isn't an issue.
Have to hold the body perfectly still to avoid motion blur- not an issue in a studio or portrait session, but not always possible in fast-moving wedding scenarios.
Nope, the D800 is NOT for me.
You try out a D800 yet? Most of my RAW/NEFs uncompressed only go up to 40-45 MB range. With the D700, they're already half the size for the same photo... 3x the MP doesn't necessarily translate to 3x the memory needed. Besides, the D800 has better ISO performance and also much better dynamic range, not to mention two memory card slots.
Then again, the D800 needs top glass for its MP to shine (like the 24/1.4, 200/2, 300/2.8, 14-24/2.8, etc.).
Only advantage of having fewer MP IMO (I shoot both the D800 and D700) is that you get more leeway when shooting longer focal lengths because the blur from motion is slightly less than if used a higher MP body.
But I love the DR on the D800 at weddings, and for group shots it BEATS the D700 easily for details.
