The consumer cameras get updated more frequently than Pro models, a 80D will likely arrive next year, possibly this fall. I have not heard any solid Rumors yet.
Beware, there are lots of websites with really unreliable rumors. Canon Rumors grades the quality of Rumors. CR1 is just something to discuss, and is not a reliable Rumor.
CR2 is from a source that tends to provide good information, and there is a backup providing similar info.
CR3 means its confirmed, and seldom falls thru.
Another Site to check is Keith Coopers North Light Images. It has a huge amount of valuable and accurate photography and printing information, and as a secondary feature, Keith Summarizes rumors so you can see ones that have been posted over time.
