You should also mention that it's a $1,000/year extention as that would influence the appraisals. Also, that name is not registered according to the Whois. Personally, I wouldn't spend $1k/year for that extention although there is a very nice domain hack I would like to register for quite a long time.
I did a small research, i don't think any .ki have been sold until now.It's a really good name for a domain even with this extension probably in future will worth alot.I would keep it if i was you.Also how much is the renewal fee?
Oh i haven't saw the htmlindex posts probably we were posting in the same time,if it's a 1k/year extension better leave it, by far it's not worth that much.
No point your overheads is $1000/year, no wonder such a good name can still be obtained. For ki, you really can't link it to anything. I won't take it if I were you. What you can do at present maybe to search through all the gaming company, see if any of their online games fit into .ki and try to sell to them. Things are most valuable only if the buyers themselves see a value to it.
