I think that it's very unfortunate for piece of hardware that cost aprox. 3500$ for 5DMarkIII, and 6800$ for Canon flagship camera 1Dx, that those new models can't produce 1080/60p, while Panasonic HDC-TM900 as mentioned before here in this post by user "stevenrrmanir" can provide that feature for $800.
Now, why Canon thinks that 1080/60p is dedicated only to very expensive cams, while Panasonic and Sony can include that feature in their cams, even at low entry models.
It's old news for them, but it's not even a fresh news for Canon???
Sorry videographers, amateurs and professionals, Canon thinks that you don't need to have feature in your newest Canon DSLR for"only" 6.800,00$, no, no... it's very, very expensive feature, you know? :

Do we have to wait another 3-4 years for Canon SLRs that will get that feature, while other manufacturers will probably offer 4k, or 8k at 120fps?
1080p/60 is really that irrelevant for all Canon users?
Really?
If so, than why did Canon started that game of implementation video features into DSLR still cams in the first place?
They started the "game", but now they don't have enough "steam" to keep up with Panasonic and Sony?
I really, really hope, that Canon users will find the "light at the end of the tunnel" with release of future firmware/software update...
C'mon Canon, you can do it, just close your eyes and JUMP !!!
Do it already... :
Don't get me wrong here, I now it sounds harsh, but it's for users sake, old, and new ones (myself included) that will walk "that way" choosing Canon as their "weapon of mass destruction" in the world of stills and video.
