On the flip side, if you have stabilization in the body, all of your lenses benefit from advances in stabilization technology each time you upgrade your body (versus buying all new lenses to get the latest advancements in lens based Image Stabilization). ;-)
I've got Minolta AF lenses manufactured 25 years ago that are stabilized on the latest Sony dSLR bodies, benefiting from advances in the body. Ditto for focus speed (as they're "screw drive" lenses and the body based focus motors in Sony bodies have improved with each new generation).
There are pros and cons to either approach.
