Wife found out / D4 & D800

Unfortunately my wife found out that I have pre-orders for both the D4 and D800!!!

I explained that I ordered both but was going to choose one of the two, but as release date gets closer was going to buy both of them. Not the right answer!!

I shoot low light and available light (concerts, events, etc.) as well as landscapes, portraits, HDR, travel, etc.

The D4 is my first choice except for the size (not ideal for travel).

The D800 is the right size (for travel) but lacks FPS and reduced low light/high ISO capabilities and file size might be overkill for multiple exposure HDR (7 or 9 exposures times 75mb).

Any thoughts especially with travelling with a D4 and HDR with a D800?

Thanks for any comments.
