When you think of the iconic last gen games - Uncharted, Mass Effect, Dragons Age 1, Bioshock, GoW, Halo, etc - they didn't start appearing really till 1-3 years after console launch. So hopefully we'll start seeing some trickle out this year like Bloodborne, Battleborn (god I get those two games confused all the time), and maybe some new shit at E3. Star Wars Battlefront should hopefully be amazing and I'm not sure if you'd call it a reboot or sequel.
but yeah sequelitis is really too much right now, the other big games are all sequels like Witcher 3, Uncharted 4, Halo 5, etc. The new IPs have all been pretty weak like Dying Light, Evil Within, or Watch Dogs.
