The Name of the Doctor: Predicted Whispermen. Didn't get so much as a Richard E. Grant in a tophat, let alone John Frakking Hurt.
Nightmare in Silver: I correctly predicted the new-look Cybermen. What I failed to predict was the sheer amount of Hedgewick's World merchandise, presumably so fans can pretend they were there as if it were a real theme park and all that. However, given how terribly naff the whole thing was, I don't think they want to be reminded.
The Crimson Horror: Still waiting for my Madame Vastra and Jenny Dress-Up Playset.
Journey to the Centre of the Tardis: I predicted ash-zombies, but no. You could always make your own by taking a Doctor and a Clara figure and subjecting them to intense heat.
Hide: Well, I sure didn't see this coming. Kudos for surprising me!
Cold War: Ice Warrior, though that was an easy one as they'd already released the prototype by the time the episode aired. This is unexpectedly neat, though.
The Rings of Akhaten: I suggested the grill-mouthed stalking thingies. But no.
The Bells of St John: Clara. Albeit strangely flat-headed and yellow of skin.
The Snowmen: Neither Snowmen, nor Great Intelligence Novelty Snowglobe, have manifested. Do they just not do merchandise for Christmas episodes anymore?
The Angels Take Manhattan: I predicted new Weeping Angel variants; we get that, and, more interestingly, this. This is also amusing.
The Power of Three: I said Character Options would be missing a trick if they didn't release novelty desktop Cubes. They didn't.
A Town called Mercy: I said this was one for the action-figure customisers, and, well, it was. You'll have to make your own cyber-cowboys.
Dinosaurs on a Spaceship: Likewise. Go buy your own triceratops (PS, isn't he adorable?).
Asylum of the Daleks: Daleks.You were maybe expecting something else?
The Doctor, the Widow and the Wardrobe: I predicted Tree People. We didn't get them, so you'll just have to carve your own.
