Yup, that's why I said won't see "many" rather than "any" genuinely new ideas. More powerful hardware will open up new possibilities but I believe most devs will use it almost exclusively to make games that look nicer but they'll play identically to what we've seen this generation just with better frame-rates, resolution, viewing distances. It's just good business sense in the short term to make the same game that plays on multiple platforms, they can use the latest consoles for the trailers but people running PS4/XB1 can still part with their cash.
I'm hopeful that in a couple of years we'll see some games that use all of that grunt to actually move gaming in some new directions but the reality is that development for new ideas is harder than retreading existing ones and that areas like AI are much much harder than having better textures.
After 30 years of gaming I'm holding out for some crazy new ideas to freshen up the endless torrent of sequels and remakes. Lately I tend to prefer indie titles where you still get some unique stuff like Baba is You or Return of the Obra Dinn, I've also played quite a few PSVR titles just because the experience is so different (even though the number of AAA titles is pretty small).
