I think that'll be a good case study. There's the old SEO myth that .edu, .gov, and .mil domain names have more SEO power than .com, .net, and .org too. Google's reply was that there's no preference for TLDs and it's only that webmasters would rather link to a .edu/.gov/.mil domain instead of a commercial one (and hence more PageRank). A study examining the ranking abilities of .com, .net, .org, cheap TLDs (.info and .xyz) and new one word TLDs with the keyword in the TLD would be good. You can't really test the ranking power of .gov, .edu, or .mil TLDs but I think the results of the test can be extended to those government TLDs too. It'll end the old question of "what TLD should I pick?" If it's found that cheap TLDs have no disadvantage to .coms, that'll be great for anyone who wants to pay $.88 for a domain name instead of $12. If it is found that the new one word TLD with keyword has a ranking benefit, that'll be great too. Pretty awesome case study IMO.
