For those that haven't heard, American pre order bonuses have been announced. I'm assuming that they'll be the same in the UK, just the shop they come from will vary.
Best Buy (or any retailer in Canada): Bret Hart playable character
Toys R Us: Undertaker's "Ministry of Darkness" gear
Amazon.com: Three outfits for Randy Orton (T-shirt, suit and referee uniform)
Walmart: "Tribute to the Troops" arena
Ministry Undertaker finally!
