New gtld is/was a nice scam and I think everybody sees it now.
After .com, is .net and .org, then there are plenty others like .eu, .co and national tld.
Then huuge gap. Then the overpriced newgtlds. Even .info and .biz are better than 99% of new gtld's that no one saw ranking in google.
There really is a reason, why .net and .org price is roughly 5% of .com, considering the huge gap between .net/org and new extensions, then with rare exceptions the value of new gtld's will be always lower than reg fee.
PS. I do not believe any numbers about "reported sales" by new domains.
