All surfers need is content in a cultural and linguistically relevant context.
Dot Com only reasonably assures that for US surfers, which is why dot US is still weak, and "Dot Com is King" for those that have no interest in how the Internet functions outside the US.
In many parts of the World it won't be the ccTLD that is the primary determinant of cultural and linguistic relevance, but the language that is used.
You can use englishgeneric.cn until the cows come home, it won't give you any kind of penetration or recognition in China. Only Chinese Script domains will ultimately give you that.
Dot com is likely to maintain its global dominance but only for those that don't insist on trying to force the English Language onto everyone else. It wasn't ever going to work and no amount of Jingoism will make it so.
