Conspiracy theory time!
Is Relic just as frustrated by the NDA and the non-existent marketing as we are and the appearance of Brits in the game files is their subtle way of telling us what there is to be excited about?
Many of the developers I've spoken to are, yes, but it's not something they can do much about. Their job is to design content for the game, not to change internal office politics or argue about brand management. A sad fact of life, I'm afraid. Do not expect change in those areas. We've had two years of this now.
As for the lines about the Brits, I'd just put it down to an accidental leak. I don't think there's anything to be read into it. Conspiracy is rarely a fruitful line of enquiry.
