<p>If the pro dealers are involved, you can expect a prosumer DSLR at least.</p>
Not holding my breath. FF is where Canon needs to fight back.
Expecting (hoping for ) 5DIV announcement end of 2014. Time line for that camera in August would of course be very nice.
If I were you and depending on what you expect for a 5D4 I wouldn't hope for your expectations.
My guess for new pro/prosumer DSLRs is:
7D2 (or what it will be called) announced around photokina, released hopefully this year.
High MP/new sensor tech FF (3D/1D XS or what it will be called) announced maybe this year, released maybe in 2015. And this won't be a 5D3 successor!
5D4 (or what it will be called) maybe announced in 2015, released maybe in 2015 as well.
But we'll see and maybe you are right.
Interesting how well Canon can keep the rumor leaks dry these times.
