Applications for new these new TLD's will be accepted from 12 January 2012 to 12 April 2012. However the approval of the .brand (dot brand) top TLD creates both opportunities and issues for brand owners.
ICANN apparently plans to allocate only a maximum of 500 .brand extensions each year, however it is expecting to receive thousands of applications (estimates are anywhere between 1000 and 4000 requests). However expect a bun fight for those names that are used in more than one context. Brands who share names are going to have to to resolve some pretty fundamental differences.
