Not only short domains , there are good number of keyword sales also.
Hope .in will become more popular like .cn by 2020. Chinese companies actively purchasing domain names for a long time.Indian companies slowly picking up in recent times.Meanwhile foreign companies are buying .in domains for their local presence.
There is an added advantage for .in over .cn. Indian companies can easily go for dictionary words whereas Chinese companies prefer short 2,3,4 character domain names.
