@Riot Better stream quality?

I noticed you guys experiment with 1080p@30fps and 720p@60fps, and I want to know if there will ever be 1080@60fps because I think many would rather sacrifice a little video quality for much more frames per second. If not, will 720p@60fps be available again?

I know that a year ago on reddit, Janook said that the network stress would be too high, is this still the case?
