I look around at who is making the money, and it's the .com's. I don't see any variance which can substantiate buying non tld's.
IDNs are .com available from a dozen or more registrars, and all under the .com registry managed by Verisign.
Verisign is going to allow .com holders to have ".com" in various languages as well, so you will have "idn.idn" (foreign language url. foreign language .com)
The same is happening with cctlds, they are moving to idn.idn.
Some are already in use, others are anticipated to be as follows:
