I'd seen on interviews and older versions of the faq that anonymous matchmaking would be offered, but I can't find it anywhere on ICO.

Are anonymous matchmaking, ladders or some kind of ranking coming in a patch, or is ICO staying the way it it?

I've got to say I was pretty disappointed logging into ICO and seeing that there was no way to get automatically matched for a game. Warcraft III, Halo, and all of the major online games have automatic matchmaking that keep the ladder from being rigged, and keep players from having to wait forever to set up a game.
