I have just used google adwords keyword tool, and i think this is promising so i won't discuss in this thread.
I'm not a huge fan of .asia and .eu, I just don't see the point. You have .jp, .cn etc. for local markets, that's more than enough.
I've found cool single-dictionary words available, but I don't need an .asia domain, mostly associated to Asian target projects
anyone from asia want to know the domain for a small fee? the keyword gets over 9 million exact searches per month lets say $50 and ill tell you
