dont know if this has been noticed/mentioned before but on play I noticed they are selling an item called doctor who anti-time device. not being able to remember this, I looked on the product information and not only does it seem to be from the christmas ep but the product information seems give a lot of spoilery background information about the ep if I am right in thinking that this is what it is about.

IS it this?

It's been out for over a year, I don't think it's canon (as in not seen in an episode), just a fun addition to the toy line

yeah, looks like you right, its just the mention of all the species involved in the christmas special that made me think i had something, oh well, just over a week anyway till we find what its all about.
