I have pre-ordered the core and was curious when the release date was. i look around an couldn't find anything on it. Anyone know?

FFG does not disclose specific release dates. They just don't. Any distributor, store, or website that does put down a date is making stuff up.

The most they have said is that it will be Q3, and it was set to On The Boat status as of 8/24, which is 4-6 weeks. Then usually another week once it goes to Shipping Now status, so we're most likely looking at...I'd say at the earliest, it could be in stores by 9/23ish, and I'd be annoyed if it wasn't out by 10/9. (Which is pretty consistent with the Gen Con debut and subsequent release of Netrunner and Conquest in years past)
