The Ice Warriors Possibly Making A Return To The World Of "WHO"

Matt Smith aka The Doctor left fans wondering if the famous Ice Warriors will be making a freezing cold return to "Doctor Who" after what he said at The 11th Hour Convention last weekend. A fan asked if they would be making a return and Smith said, "Yes" and smiled to the audience and then went onto the next question. No one knows if he was just saying that or if it's actually true.
The shows head writer, Steven Moffat has said in the past that past villains and monsters will be getting revived and brought back to the now "WHO" universe, so this could be true about the Ice Warriors. The last time they were on TV was back in the 70's "Doctor Who", so it would be good to see them return.
