I still wouldn't budge. The appeal is a smaller package that's equally as capable. If I still have to pack a Canon 70-200 I am not really saving any weight. Their bodies still seem one dimensional. Hopefully someday they will have the complete package.
For many of us, the smaller package isn't a consideration - more often than not, it's actually a hindrance. Sure, thinner and lighter (not necessarily smaller in length and width) is good, but not at the expense of functionality - dedicated buttons instead of having to scroll through menus or play with multifunction buttons, dual card slots, etc.
The attraction, rather, is in the sensor. If you shoot mainly at low ISO (1600 and below) and need either high resolution or high dynamic range, Canon sensors haven't been able to keep up or some time. Nikon has (largely due to using Sony sensors) but is lens-limited - very few non-Nikon-mount lenses will fit onto a Nikon due to its large flange distance.
So far, Sony has delivered a body that can take almost any lens and put it in front of a top-of-the-line sensor. AF is slow and mediocre, but most people using it that way can put up with it for now, since they're mostly landscape, studio, architectural, macro and other non-moving/slow-moving-subject photographers. In a way, it's similar to the 5D2 - all sensor, and not much else. But a body which could AF well (delivering the functionality of the 1Ds3 instead of the same-sensor-but-different-functionality 5D2) would be far more versatile - no need to pack a 1D4 or 1Dx body along with the lenses and Sony bodies when going on a mixed landscape/wildlife trip.
