What would a seventh gen throwback game be like?

Since N64 & PS1 throwback games are pretty popular, and I think we've gotten some sixth-gen throwback games but I can't name any at the moment, it seems inevitable that a seventh-gen throwback game might come along at some point, but what would such a game be like?

Would it just be a stereotypical grey-brown third-person shooter played straight, well that's certainly what most people think of when they think of seventh-gen gaming but that's not all that was happening, the seventh-generation was also dominated by gimmick-ey peripherals like the guitar hero controllers and the Wii's controllers, and it was also the era of the Wii being super popular, so would a seventh-gen throwback game involve COD Soldiers getting isekai'd into a fantastical JRPG/3D Platformer?
