Will we see games in 4k next gen?

So I know that 4k is pretty new and that it wasn't even in till this gen that we started to mostly 1080p games so do you think we will start to get 4k games next gen? I am going to say yes and hear is why. Ps3 and xbox 360 where mostly 720p with a few 1080p games and now this gen a lot more games are 1080p instead of 720p. I think we will have something similer next gen with 4k games. I think next get most games will be 1080 and a few will be 4k then I think by like then gen after so like ps6 most games will be 4k. I wanted to make this a poll but messed up I don't know if there is a way to edit to make it a poll but if there is can any one let me know.
