I don't think you'll ever see a $1 million IDN sale.

The names without traffic aren't ever going to reach that high, and those with tons of juicy traffic (post-adoption, post IE7 etc.) are going to be making so much money at that point that their owners won't sell - period. Just like as in ASCII right now there are about a dozen mega-domainers sitting on huge portfolios who never ever sell anything - and why should they when they're making millions and millions of dollars a year from parking income.
