It seems as if both GDI and Nod have internal conflicts this time. With GDI it's a fight over whether or not to use tiberian weapons in what is assumably a desperate moment in the war. Director Boyle's for it; General Granger's against it.
With Nod it seems to be a dispute over the aliens. General Qutar views the aliens as a greater threat than GDI. Kane thinks differently.
Looks like both campaigns may fork, quite possibly even having different endings.

So, based on the trailer, whose side would you chose? Boyle or Granger? Kane or Qutar?
