Good single word .cc sell well from time to time, but I don't think .cc will take off anytime in the future. The examples in the original post could sell for xx or xxx, maybe even low xxxx if the right buyer comes along. I think the term 'vanity url' suits .cc very well, because they are mostly sought by end users or domainers who like the word. I had an enquiry at Afternic just last week on a four letter one word .cc I have that does get a little traffic - will see how it goes. I sold one .cc a few years back for just over $1,000 and the buyer used it for their website - using .CC to stand for 'China Customers'.
