Upgrading from 750D

I am considering upgrading from the 750D, I still think it is a great camera, however would love to upgrade.
I am currently using the 24-70 ef canon and a sigma 70-200f2.8. I am mainly focused on landscape photography with the occasional wild life photos when they arise.
Just wondering what you would upgrading too, I am definitely considering second hand.
With the announcement of the new r5 and r6, I expect to see a lot more cameras for sale, is there a particular body I should be looking out for?

Keith asks a very (if not "the") pertinent question: what is it about the 750D that is lacking? Why the need to upgrade? Of course, you might just want a change - that's fine - we aren't here to judge! Still, are there features that you have on your wish list?
In general terms, for landscape you might find some benefit from thinking about going full frame. You don't give an indication regarding your budget, but a Canon 5D III may be worth a look. Also, if you are confident your technique is up to the challenge, I know you can get the 5DS and 5DSR now for approx £1k on the second hand market. I've used a 5DS for wildlife, although like you, landscape is my main genre, and I can report that it copes very well. Yes, it lacks the brilliant high ISO performance and frame rates of some, but it still does the job. The main issue with it is that it is an unforgiving beast in terms of technique and the files need a computer that can cope. Finally, don't rule out some of the Sony A7 bodies - with an adaptor you can still use your existing lenses (albeit some of the native sony AF features may be lost).
