i'm sorry but your pretty much wrong if you think all Dynasty Warriors are the same.
in fact Dynasty Warriors 8(Shin Sangoku Musou 7 in japan) is probably the best in the series since it was a HUGE improvement over 7 and the older games.
faster gameplay, a change of musou system, more enemies and battles, tons of characters, more cutomization(well for the upcoming Empires version)
and lol Atlus, i'm sorry, but they've also been making the same games SMT, Persona.
only Etrian Odyssey(which only recently got a sequel after a long hiatus) and Catherine are they're new games this generation.
Trauma Center series is pretty much dead unless they changed they try to revive it with a new game like Etrian Odyssey did.
Tecmo Koei has also upcoming games like a new version of Warriors Orochi 3, Dead or Alive 5 Ultimate, Ni-Oh!, new Atelier games etc.
