The current series is up for preorder here and in the US I am in two minds as to whether to go ahead and preorder the UK DVD or wait and hope that there will be a blu-ray version in the US. I have previous series on blu-ray from the US but I was disappointed when they decided not to release a blu-ray of series 18 last year. Not to mention the fact that they haven't released it at all in UK. I wish the BBC would get their act together with TG releases here. It is British for gods sake. They are getting better.
