Those type of interview are pointless if they dont ask the question that EVERYONE is asking. 1080p 60fps.
In some games it's just not technically feasible as they are CPU bound games. For instance Destiny 2, they delivered native 4K with a rock solid 30fps but Bungie said that they could not deliver a 60fps mode due to the game being CPU heavy with the amount of enemies on screen at once.
The CPUs in the enhanced consoles are barely faster than the base console variants. They are UNBELIEVABLELY slow. Low end desktop CPUs are magnitudes faster than what we have in these enhanced manchines
