Exactly! I love how is rumor is blowing up all over camera forums now though and people are trying to stop others from buying the current version 
I love Canon Rumors though... But I really don't pay much attention to the CR1 stuff at all for anything more than entertainment. CR2 gets my attention and CR3 is usually on point.
But in all honestly, if the 24-70 II did come out I would expect IQ to be slightly less impressive as the current, non-IS version. Due to more elements inside the lens and all that. Now I know in the case of the 70-200 f/4 and the IS version of that lens, the IS version is noted to be sharper. However, the IS lens was released 7 years later. The 24-70 II's were developed at the same time with the same tech.
I am sure the IQ difference would be negligible though and most would pick IS over the sharper image. I have been fine without IS though honestly... Most of my stuff is moving when I shoot at such high ISO or I would just use a tripod and shoot at ISO 100... So in a way, I can deal without it and would most likely chose the non-IS version anyway if IQ was superior.
