Christmas 2008 Special Title Rumour

There have been rumours going around lately about the title for this year's xmas special. The title that has been speculated to be is 'Ghosts in the Machines'. This would sound like ghosts are inside the Cybermen! Although, this may not be the real title, because last time there was a rumour about the title for episode 12 of Series 4, and it ended up to be completely different! But anyway, there's a little treat, as we've got a long time until Christmas!
