...I will hold off on upgrading until Canon gets a clue, or make the switch to Panasonic, perhaps Sony, (who do appear to have a clue).
A clue about your specific needs, that is. I wonder if Panasonic or Sony have a clue about how to make products that appeal to the majority.
The popularity of a camera like the 70D (not to mention the 5D3 when ML came out) suggests that your "majority" is very likely a minority. Most buyers will be looking for integrated imaging devices, not specialized stills or video cameras. And since 4K is the future, while HD is the past, that is what is going to drive those buyers, especially when they start to buy 4K TVs and see the difference in quality. People who buy 4K TV sets (in other words, high end buyers - the same folk who buy most high end DSLRs) are not going to be interested in shooting HD afterwards, they will want 4K. So who will they turn to? Apparently that isn't going to be Canon.
Something tells me that by the time 4K displays go mainstream, Canon will have cameras for the mainstream to go with them* -- if success in the DSLR market requires it. While those who adopt 4K TVs early might be the same slice of the market that buys high-end DSLRs, I don't think they comprise a majority of the market Canon depends on for its bread and butter. I don't have a source (so someone feel free to correct/corroborate), but I believe Rebels and 70Ds make up a far greater market for Canon than pro gear.
We have to remember that this is about business . A tit-for-tat strategy on feature set vs. feature set with the competition does not necessarily mean good business. Only Canon decision-makers have the inside information to support their strategy, and the proof will be in market performance and shareholder value.
*Imagine how awesome 4K with DPAF will be!
