So, do you capture video at all or just stick with stills? For image quality of course I'd go for a DSLR.
The point and shoot would primarily be for video clips 1-2 minutes and for the days when I don't want to lug around a DSLR.
I do occasional videos, then I use either my wife's Panasonic TZ10 or my son's Canon SX30is (slight preferance for the Canon in video).
I have considered upgrading to the d800 for video in a single body (and selling the d700) or adding a d7000 for macro and video (pixel density of the d7000 would help with Macro). I am leaning towards the d7000 since even though it would result in two SLR bodies, it also gives me a backup body, costs much less and would work about as well for me.
The d700 for stills, low light and other demanding stuff.
The d7000 for macro, long telephoto and video.
Not sure yet. If cash were not an issue, I'd just get the d800 and call it good.
I found out my wife recently (as in a few days ago) broke her camera so I might use the replace her camera gambit to sneak in something I also want.
