That's what I would tend to think about the 5D4 announcement as well. However we DID just have the 5DS arrive. So it's like they went through the 10 year anniversary with nothing to show for it. I think the 5DS gets some breathing room for sales before they show off the 5D4. Maybe we see a release next April with some announcement late this year. August I think we'll see an official announcement on the 1DX II. I don't see that camera missing the Olympics next summer.
It wouldn't be much of an anniversary if they didn't launch the 5DMkIV! This video looks like a precursor to an announcement. It may not be August but I think we'll see the MkIV in 2015.
BTW My lens bet is a 70-300 IS USM replacement. I don't think it gets STM however.
