Ahh.. heh, don't get your hopes up. I asked in at the HMV on Oxford St., as I only work about 5 mins away from there. They've said 28th, as have EB on the same street. I think I know what you are talking about, but I don't think "one of those times" is applicable to JO.
Still, I'll check during lunch today, just like I have been for the last 4-5 days.
You know.. with the amount of people asking/calling about dates, all these sales assistants must be thinking that there will be some massive invasion when the game hits the shelves. Mind you, they wouldn't be wrong for thinking that.
