What are some things that should remain the same and what are some things that should be changed for the new Modern Warfare? Should Infinity Ward design the game or should it be a different company?

treyarch is gonna make the SICKEST game ever.

between treyarch and infinity ward, i think that infinity ward has dominated the call of duty series with the modern warefare's but treyarch could give them a run for their money with black ops so until then, i think it could go either way with who could be making a new modern warfare
