By player do you mean Hilbert/Hilda or the ones we are using currently? If it is either hard to say. I can't really see the player siding with any of them. Especially not the Black faction as it seems you and the rival are working against them. As shown in the gameplay and video (which also includes Cheren opposing them as well).
Also curious as too how Looker will come to play with Plasma or World Police since he was pivotal in arresting all the Sages.
Also speaking of Sages and Triad I hope we get to battle them I am interested to see how their teams would be made up of.
