In my ideal future, some able-handed team like Sanzaru would make a reboot of Jak and Daxter that kept what made it good and updated some of the more antiquated features, and then for the TLOU team to do a game from a different IP since TLOU is a game that doesn't need a sequel.
In Jak, the platforming was a lot of fun, as were the seamless worlds, interesting guns, varied vehicles and fantasy elements. The collecting got burdensome, the camera controls were bad, the difficulty curve was poor and certain stages were filled with elements that made them cheap. Jak in II and 3 was a bit too angsty, and the vehicle sections in 3 were far too numerous, so there's definitely room for improvement.
Haven't actually had a chance to watch the keynote, but I'll go ahead and do so now.
