.de is by far the most dominate and I concur with Adoptable that .us has a chance to possibly rival it, however, I believe that .eu will in the long run become a force as well along with .in and .ca.
I think you're right about .in and .eu. Although not available yet, it probably has the best potential in a class with .de and .us. I think ccTLD's generally will appeal to the end customers within that country though. Canada's .ca has one strike against it, which is the smaller population of Canada at only about 32 million, which is about half that of UK and Germany. Also, half of Canada speaks French adding another word/language division.
I think the popularity/value is a formula of several components:
1.
Population.
2. Spendable Income of the inhabitants of the country. (consumerism)
3. How connected is the population to the internet.
4. How capable are the residents at buying from the internet (credit cards, paypal, etc.)
5. How much censorship is there of the public by the local government.
On a world scale, I think .in has the population, but is just just growing in ability to consume more than necessities by the population as a whole. .eu has a broad appeal in the whole population of Europe who are major consumers.
The southeast asian ccTLD's will be popular there, but you need to understand a different and difficult language with different character sets. therefore I don't see much value in .cn for english names.
If Australia and UK would offer second levels, I think they would go over very well.
