Anyway the speed and AF and all sounds like out of the park, awesome.
The sensor is what it is. It would be DOA for a 5D4, but it's probably OK for a 7D2 (although not ideal and I certainly feel for the one body shooters who'd use this as their main landscape cam too).
The video looks pretty punted though in terms of quality.
If you don't hit DR-limited scenes much and never shoot video it's a total home run. Grand slam even (assuming it lives up to the words).
If you were looking to it for video it's a D+.
If you wanted an action cam plus great all around aps-c sensor it's mixed, great on the one hand and stuck in 2007 on the other.
I'll preface this by saying I don't really shoot video but that said, I think it will hold it's own pretty well considering the smooth AF it appears to have from the Canon promo "Cello" and the "Making of Cello" I think will be a hit with the entry level video guys especially when coupled with the lens system Canon has. Granted, it's not a nice as the 5d3 video, but that wasn't to be expected. Physics. However, that short they made at 3200 ISO looked pretty darn good and the focus racking looked darn good to me. Put that little camera with a Ninja and it's a good little set up I'm betting.
I haven't really seen the video quality of the 7d mark ii because the cello video on Canon's site doesn't allow me to change the resolution or even full screen it but if you're saying the video is worse than the 5D3 then that is pretty sad. The 5D3 is pretty S___ now for video. So if this new cam is worse, then oh wow am I laughing now.
