Bleedingcool.com describe it as: "Based on the same font, it’s black with silver studs, looking all Dalek-y. Something special for the season opener?
Not a bit of it. Bleeding Cool have been told from BBC sources that the title will change with every episode to reflect the content. So Dinosaurs On A Spaceship, for example, will see the logo covered in scales…"
Radio Times say: "Look out, too, for a tweak to the title sequence – it’s the same “colonoscopy-in-space” effect but with a bluey-green tinge and a redesigned logo. The Moff tells me that there’ll be a special logo and title fonts to match all five episodes."
A few minor changes include a different credit font which fades in differently and a movement of the DW Tardis logo.
