Why people still calling Ninja Gaiden Sigma 2 PS3 exclusive?

Can you play Ninja Gaiden Sigma II on any other platform?

Going by that logic, Ninja Gaiden II would be exclusive as well since it's obviously differs in certain areas from Sigma II.

If you ask me, either both should be considered exclusive, or neither, with no middle ground.
