No dont take it, this extension easily surpasses that of the org/net and maybe .com as .cn will be placed on all asian cellphones by 2067 . The ONLY way on the net will be .cn also it is used for many country codes not just the popular Canada !
On a serious note my guess would be the buyer has this in mind...maybe ?
