No clue on the PDI front, but I agree with missing Iris. I suppose we'll just have to keep anticipating the new DLC and speculating on what those maps will be instead. Or whether or not CoD4 will keep beating H3 on the Xbox Live charts once that DLC is out.
Yea, Omega is doing a bit of research into some stuff just to pile up a good pool of facts to pull from. There's a lot of info connected to IRIS (tightly connected and loosely connected), and we need to pick and choose what to cover.
