Matt Cutts on his Google+ page wrote that new TLDs will not help the raking of the websites.
He said, “I don’t expect a new TLD to get any kind of initial preference over .com, and I wouldn’t bet on that happening in the long-term either.”
This came as the response to a claim in markingmag.com.au, where the CEO of a Domain Registrar said that new TLD web addresses will be given priority by Google as over .com.
Here is what Matt exactly wrote, “I read a post by someone offering new top-level domain (TLDs). They made this claim: "Will a new TLD web address automatically be favoured by Google over a .com equivalent? Quite simply, yes it will."
Sorry, but that's just not true, and as an engineer in the search quality team at Google, I feel the need to debunk this misconception. Google has a lot of experience in returning relevant web pages, regardless of the top-level domain (TLD). Google will attempt to rank new TLDs appropriately, but I don't expect a new TLD to get any kind of initial preference over .com, and I wouldn't bet on that happening in the long-term either. If you want to register an entirely new TLD for other reasons, that's your choice, but you shouldn't register a TLD in the mistaken belief that you'll get some sort of boost in search engine rankings.”
