I'm about 90% positive we will get to keep our characters. Because their promo or whatever you wanna call it for preordering the regular, it said "early access to the Vanguard Armory" and something extremely similar to "gear up with all the best stuff for day 1". So, I think we will. At least, people who preordered to get the beta and not the ones that got it for free (the xbox 360 got free beta starting day 2 or 3, idk about other consoles). Well, that's just my opinion. Not a fact.
