Well, I just ordered mine yesterday, and it is back ordered as well.
When you go on the page before you order it, when it gives the details about the reward, it says in bold 'Will fulfill by late January'. I have a feeling this is talking about the shipping. So if people are ordering it now, I have a feeling that it will be a while until we get them, by (hopefully like it says) late January. Or at least shipped then.
I would expect to wait another few weeks before the 'shipped' confirmation.
