Wasn't Spartan Total Warrior developed by CA though?
Yes that is correct. Please forgive my ignorance. I was speculating on possibilities, with no in-depth knowledge. I will be sure to do my home work in the future.

Theory is wrong.
In that case, I am happy to be wrong. I too was initially glad to hear that SEGA’s involvement. But believe that they are, and will be operating only in the same capacity as Activision and Electronic Arts before them, with little or no concern with the development and maintenance of the actual games.

But I would love to be wrong about that also
