D90 video quality in low light ?

Hi,

I'm interested in the d90 video capability (not as true camescope but to get some short clip on vacation, I always carry a P&S for this) and was wondering if, due to the sensor size, we could have low light video with outstanding quality ?

THAT will be a real incentive for me, daytime quality for vieo in low light thru pixel binning, my F20 is good but not amazing in low light video.

Is this possible or is there other parameters that will prevent it ?
