IMO, this is nothing more than latest product of the never ending 'feature churn' marketing program that all camera makers are so fond of.
The larger, more accurate viewfinder is most welcome, but is also the only significant improvement I see.
IMO, none of the other new wizbang features will do
anything to actually improve my photography.
Dual axis electronic level? C'mon! That's what the viewfinder is for!
5 gajillion AF points - none of which will work on a low contrast twilight sky.
More pixels, more noise.
The supposedly improved weatherproofing sounds useful, but if Mike seem to think it's no biggie, I'm not about to disagree.
Guess I'm just a jaded cynic.
