If this was Apple......
All they would need to do is place one Ad in a small town paper that a new "shiney" would be available from midnight on the 25th and the ques would be round the block, the worlds press would go crazy on rumors etc, on the 26th when it turns out its a new camera adaptor for the iphone5 the fanbois would be making excuses why its not the mini and Apple would have got a free sample of how much people want it.....
As this is MS i don't expect there to be any ques let alone camera teams from the news orginisations......
Dream on Bulmer, not many will buy from your pop-up stores as those that do want it soonest will buy from places they know they can return it to if its faulty etc.....
