A *ist D sensor can theoretically resolve 1004 horizontal lines (that's
2008 pixels high divided by 2), and since the sensor is 15.7mm high,
that's almost 64 lines per millimeter.
So, yes, most of the time, for most people, and for most lenses, the
sensor will out-resolve the lens, and going up to more pixels won't help,
unless the sensor dimensions are increased.

If you expect the captured images to be as sharp as the sensor will
allow every
stop from wide open to stopped right down you'd be disappointed, the
laws of
physics won't allow it. However at the sweet spot of most lenses a
sensor of
10MP in an APS format will work quite nicely resolution wise. Any DSLR
sensor
beyond that density would deliver specs for sales and marketing but
nothing
more for the photographer.
It's actually quite amazing at how low the delivered resolution of
lenses actually are in normal picture taking situations. Very few, if
any, lenses can deliver more than perhaps 60 lpmm in normal conditions.
