Probably good odds on that Reezy. Most add on packs have not received release dates, and if they do, it's like 2 or 3 days ahead of time.

Based on the trophies showing up, we should see the pack this week or next. I'd bet on this week myself, because the Killzone 2 trophies just popped up and that pack I bet will be showing up this week as well. It's a pretty well established pattern on the PSN. The trophies show up, and then the packs show up either that Thursday or the next.
