GameStop has the Gray Fox/Fox Blade preorder bonus, but Microsoft has the 1600 MS points bonus.

What are the odds on the Gray Fox skin becoming DLC in the future? They're already giving it away for free to all EU players.

Eventually, pretty much all pre-order DLC goes up for sale.

Very likely that it'll either be DLC or unlock able. Probably the former. It'll be about 400 points though. 1600MS points would cover that.

Microsoft points seems like the obvious choice to me.

Points are money! Go with the money and just buy the skin when it goes up as DLC, that is if you still care about it by then, if not you're still left with $20 worth of points!

I don't even know how this is a question? A skin which, in my experience, always suck because they seem out of place, or free money.

I think BestBuy is still giving a $20 certificate. There's that, too. I don't have any Microsoft Stores nearby. >.>

I preordered at GameStop for the costume.
