AA filter question - Joe?

Looking at both the Sony NEX-7 and and Nikon D800 pixel density, it seems to me that the sensors can now out-resolve most of the lenses used with them. Does this not remove the requirement for AA filters? Apparently not, otherwise the cameras would not be so equipped (D800E excepted).

Can anyone bring me up to speed here? Joe?

Thanks,

Dick Frederick
