The same way people have received the majority of Canon's offerings in the past year. People will read the specs and:
•First, scream and cry about the lack of megapixels and dynamic range.
•Then, complain about how it's far too expensive and that Sony and Nikon have xxx for $xxx less.
•Flood of posts from people complaining about how Canon is neglecting their customers because they personally wanted a 5D4 or 1DX2 instead of a 7D2.
•Then talk about all the stuff that they hope Canon addresses in a future firmware update.
•Then get antsy about pre-orders and shipping and create threads asking if anyone has gotten theirs in yet.
•Then when it takes a while, we'll get a flood of "I'm switching to Nikon" threat posts and demands that Canon fix their production lines (regardless of natural disasters).
Then when it finally comes out people will talk about how awesome it is and how much they love it, and how they never doubted Canon for a minute.
