I dont think it will be a system seller...
Primarily due to the fact that Killzone 1 did'nr get great reviews and was not picked up by a mass audience...so it doesnt have a HUGE fan base lets say as Halo?
Halo 1 did'nt sell many Xbox's back in the day...when Halo 2 was released Xbox numbers increased sales wise....then the real console seller Halo 3 was released and it sold 360's like hotcakes :p...
What Im trying to say is that in order for it to be a system seller it would have had to acquire a huge fanbase prior to this sequel
