I guess that .co.uk's are going to be slowly replaced by the .uk extension. Police.uk, nominet.uk, gov.uk, etc already did it. I own a small portofolio of decent .uk websites however, I see them being valued way less than the .co.uk ones. Would you sell them now for a lower price or keep them for a couple of more years and wait for the transition? What is your opinion on the .uk and .co.uk domain differences?
