I'm okay with 3 FPS on the 70D if everything else is dramatically improved. Heck, I'm okay with 1 FPS. I'm not a "spray and pray" kind of guy and my subjects don't demand it. In fact, with a flip out screen, I can't imagine the target audience is either. I use live view focusing quite often and while faster focusing would be helpful, faster FPS would not be.
Having said that, to get me to upgrade from my 60D, they need to release a FF with a flip out LCD (I was initially hoping that would be the 6D). Then, they can have my money. Until then, probably not!
Also, this is an EXCELLENT point
I don't read Japanese, but the characters after 3.0 don't match the ones after 10 in the 7dii description. Maybe it means 3.0 inch screen?
