I love that of the 4 guests announced as of this post, they are all Doctor Who related Someone like David Tennant or Matt Smith would be INCREDIBLE, but I shant hold my breath. But I agree with previous post that Paul McGann was surely a favourite this year, he was fantastic.
Would love to see some of the following;
Terry O'Quinn or Henry Ian Cusick from Lost would make my life, but unlikely to happen!
Sarah Douglas - after she had to cancel this year
Jason David Frank
Ray Park
