I don't know if this has been mentioned before but I noticed that in the E3 trailer, the strip didn't have gates seperating diffrent area's like there is in the real game. For Example: there's the area with the Lucky 38 and Gommorah, then the area with The Tops, Ultra luxe, and LVB station. And lastly there is the area with Vault 21, Michael Angelo's work shop, and the NCR embassey, but in the E3 trailer they're all together without gating, I wonder why?
