EOS 70D & EOS 7D Mark II

For the Canon 60d / 7d replacements to be successful they must move away from the present pixel pitch and increase the MP count. Smaller pixels in newer sensors are not as bad with noise and sensitivity as previous generations (this is born out in Sony professional video cameras) just tweaking the present 18MP sensor is not enough any longer.
The biggest issue for Canon is NOT cameras or sensors but lenses and resolution many fail already with 18MP sensors to be sharp particularly into the corners lenses are seriously lagging sensors with many  basic designs 10-15 years old their past retirement but hugely expensive to redesign & re-tool.

Except that Canon would have had to have different camera body models because radio spectra and requirements vary from country to country.

Nope. Just another urban legend.
Canon is selling its Speedlite 660EX-RT and trigger ST-E3 globally.
These devices are apparently using the very same frequency range/channels everywhere. 
Otherwise we would be seeing product variations - like "model A" or "B" ... or "Euro" vs. "US" vs. "Asia" type.

You know the quote "The best camera is the one you have with you?"  Applies to flashes, too. 

Yes ... but it makes you lazy too .
You end up using the on-board flash rather than an external flash, which you can bounce or use with a diffuser.

So, I'm actually all for removing the on-board flash on the 7DII. 
I'd rather have WiFi (and a bult-in radio transmitter) than an on-board flash.

Actually there is a 600EX (no RT) for what I assume is because of this reason.  According to Wikipedia, the RT system is approved for use in 58 countries, so no, it is not global.

Maybe you do.  I certainly don't.  If I expect to need a flash, I bring one, and I use it—the on-board flash stinks on ice with most of my lenses because they're too long and it's too low.    But it is better than nothing for quick shots when I wasn't expecting to need a flash, which does happen once in a while.
