Promethean vs the flood!

I would really love to see the prometheans dominate the flood in a later game. Yes the flood is still out there. However the flood/grave mind was destroyed in halo 3 in that area of the universe. They come from a planet in the dark corner on the universe & inhabit some forerunner planets as we seen in Halo Wars. Now for the question. Would you like to see how a battle plays out between the flood & the prometheans?

Yes, I think it would be cool if at one point the Chief, the Prometheans, and the Storm all team up to fight the Flood, that would be pretty awesome.

I’m thinking that the prometheans will help humanity face the Ancient Evil later in the trilogy.
