I just got my nice new G5 delivered today 
Its what should have been produced in the first iteration because it now has two thumb buttons instead of one large one. The scroll wheel now seems a little better - but not hugely - and it's now easier to click the middle mouse button. Also the mouse seems quieter than its predecessor as now the thumb button(s) are almost silent and the scroll is a little smoother.
I have one noticed one sad fact though. A drop in manufacturing quality
The mouse itself appears to be fine and feels great...but its the little things....
The box of weights that comes with the mouse have subtly been altered to something that is obviously cheaper to manufacture. The box itself is marginally larger, while the weights themselves now lack that little rubber seal around the middle that keeps them tight in place in the cradle. Also the foam used for the box is cheaper. Its not a big deal - but its a drop in quality and sadly that's the way with these big companies.
I would still recommend this mouse though, it's a welcome update if you have missed the seconds thumb button!
