A leak would be information Bethesda wouldn't want getting out. This would merely be information that subscribers would get earlier than everyone else, and would encourage others to get subscriptions. How is that bad business? I personally don't know when retail will get the new issue as I have never paid attention, but it is the February issue. I would at least expect it a week after subscribers get it.
I obviously meant scans of the article hitting the web. Who's going to buy a copy if there are scans available a month in advance?
Anyway, so we could settle this, I just called Gamestop. They don't have the current issue (Tomb Raider) on display yet, but they will in the coming days. And I specifically asked him if they put it up within the same month. I got my issue on the 10th, and somebody in the speculation thread got it even earlier than that, but just because we get them a few days earlier doesn't mean we get them an entire month earlier.
