This is indeed to be expected, and, as usual, trolling will come from the same Wonderful Sony Fanboys, never from Nikon or Fuji.Prediction: Canon will release an awesome camera. The perpetually negative, who'll never buy a camera at that level no matter what, will %itch and moan and tell us why they will switch to Sony if Canon doesn't "get it right" in 3-4 years with the 1RX II. I'll recycle this comment at that time. Oh! And we'll hear about all their friends at the local camera club switching too. Meanwhile, Sony's market share will slide to 8%. We'll also keep hearing about how an empty tube (adapter) destroys IQ and is a potential point of failure, and complaints it doesn't come in white to match their big tele lenses. We'll get links to all the articles and YouTube videos they think prove their points. In the mean time, somehow people will still be taking great photos and videos with piss poor Canon gear. Oh! And all the design experts / engineers who'll fake knowledge they gained thanks to google will be there too.
But you are right: the camera will be awesome!
