So I will not bet on that.


Not neccessarily. Current IS systems are very light, as are lens barrel materials--not to mention new lens designs and special elements. With the introduction of Sony/Ziess and Nikon 24-70 variants (possibly even Sigma's new 24-70HSM--which is very small) I believe they may have lit a small flame beneath Canon's a**. The lens is most deffinitely due for an update and I honestly believe it will happen soon *crosses fingers*. We shall see.
