My only thing about the leak is this.... If they didn't plan on releasing the jerseys until 2015, lots of people on the fence would come to terms with the home and buy it anyway. So why give them a jersey they potentially like more and only buy one.
If they release it in early 2015 and its this sexy, now you're buying two jerseys. Maybe they don't think they'll lose money since so many preorders are sold out already, but my gut is they didn't want anyone seeing the jersey for fear of people only buying one instead of two.
