Maybe not in quantity, but I agree with you in terms of quality. 2018 has an impressive number of AAA games releasing. But if tlou2, Death Stranding, and Ghost of Tsushima all release in 2019, I think it will very likely beat out 2018, for my personal tastes.
2017 was great with Horizon, GT Sport, UC, and Hellblade, 2018 looks good with GoW, Spiderman etc, however I am most intrigued with 2019. Death stranding uses Horizon engine, TloU has of course Naughty Dogs excellent engine, Ghost of Tshushima with Sucker Punch new engine (their previous engine in InFamous was the best at the time of PS4 launch). Such a heavy lineup of games with 4k game engines, maybe these are the lineup of for launching something else too.
