Interesting topic!

Here's my take...
* With all other factors being equal, more megapixels will give better IQ except in high ISO.
True, but I'm not sure about the high ISO exception anymore... The D800 surprised my with it's high ISO performance. I guess we'll have to wait and see some more new models.* Raw files opened in Adobe or in DPP will have identical IQ.
Honestly, I have absolutely no idea on this... Probably I've ignored the topic all this time to keep my blind faith in Adobe applications intact... 
* In real life situations the result from Zeiss lenses will be mostly indistinguishable from Canon lenses, all other factors being equal.
Looking at the MTF values of Zeiss lenses, I gotta think the above statement is false. It's gotta matter somewhere!* The 5d3 is the camera to grab when getting the photo is of utmost importance rather than D800.
I don't think using the D800 is any trickier... I'd have to assume the above statement is wrong.* Nikon makes better wide-angle lenses including wide-angle zooms than Canon.
I know some friends who are a little disappointed with the 16-35 but I personally have no experience on this...* If the user understands Photoshop properly then Nik softwares are redundant.
True, but Nik and similar software also make life a lot easier, so I can't say they're totally useless.* Film has lost the battle and digital rules and even looks better.
Defiantly true.* Chromatic aberrations and lens vignette characteristics of a lens do not matter as these things can be fixed easily in Photoshop.
To some extent, true... As a general statement, false!* The IQ of 1dx and 5d3 at ISO 100 will be same.
I doubt it... Two different sensors there and that's gotta mean some difference in IQ one way or another...* Cropping in camera (1.6 factor) is not the same as cropping equal amount in post on a full frame camera.
If the FF camera has 1.6x more pixels than the crop camera, then it's the same thing. If not, see Neuro's explanation.* Mac computers have no real advantage over PC when it comes to processing photos.
True. I happen to find PCs to be more powerful and versatile.* 99.9 percent of equipment complaints are user errors including the 5d3 criticisms.
False. I've had my hands on many defected gear.* Canon will announce a high megapixel camera within six months.
I believe so... Maybe a year if not 6 months.* 1Dx will ship in reasonable quantities and will fill in the initial demand mostly.
Doubtful...* 5d3 will not eat into the sales of 1Dx.
True. 10fps and war-proof body is a must for some photographers and they will use nothing but a 1 series camera.* New equipment may not make better pictures but certainly do help in making better pictures and people should stop criticizing people who want to buy new gear.
Hell yeah! 
* People who regularly visit photo forums or for that matter ‘pixel peep’ can also be wonderful photographers.
Most probably! I believe there are many amateurs here who are more knowledgeable than many pros...* Manuel focusing can be learned with practice and once second nature, it is almost as fast as shooting with auto focus for subjects not moving so fast.
I doubt it...* It is ok to use auto exposure modes available in camera and that does not make anyone a lesser photographer.
Probably ture...
