Initial thoughts: front end looks like a beaver and the steering wheel looks like it was mounted upside down. Interior looks amazing on other photos, but we'll see what BMW does to the interior when it's ready for release.
CarWow have a good video on the iX. It appears to be an X5 sized SUV, isn't that bigger than the Q4? The facts and figures are fairly impressive.
Looks wise, I quite like it from the front on view. Looks pretty streamlined. The rear is pretty bulbous, though, sort of like an estate/sports wagon rear-end. Should have a spacious interior and boot though.
