I would probably agree with you, but there are a few things in the mix.
First this one, Forza 6 will probably run on DirectX 12. Which should enhance and improve things, plus they have had a few years to work on the console, over the launch game Forza 5. I think there should be some significant improvements the look of the game.
Second, Forza 5 seemed to be missing a number of things, tracks and stuff, that people expected. So my impression that it was a little disappointing for a Forza game.
Forza 5 introduced us to DriveAvatars. Forza 6 should have better graphics, more tracks and cars, and just elevate what Forza 5 did. Plus who knows, maybe something new (like plane races or something) that we haven't don't know about yet.
