Time will tell but my friend has been right about things at SONY, Canon and Adobe before.
Time will tell indeed. You should have ended your post with 'You heard it here first!'
Your friend seems to have a bit too much insider knowledge to be a real person. Unless he worked at each of them and you mean during the respective periods he had some knowledge of his current employer.
Also, how does Hasselblad has anything to do with it? Do they make FF sensors? And is it a good idea to ditch Sony as a sensor supplier for Nikon? Companies do make strategic mistakes, you are right.
As for 30 FPS at 50 MP... Meh. How would Hasselblad develop such speeds? Reading through the Brust speeds of their current line up, the Canon R looks like a bloody speed demon, even if you turn on focus priority!
