1 character .biz names about to be auctioned

The Webnames.ca newsletter points out that starting September 23, 1 character .biz names will be auctioned off.   That means addresses such as 1.biz, and a.biz . It will be interesting to see what kind of money these go for.  On the one hand, single character domain names are as easy to remember as they come.  But on the other hand, they are not intuitively descriptive or obvious ones to try unless a business has some customer connection with a letter or number.  And most people don't think of .biz as a TLD of choice.
