According to the latest WHOIS records, Microsoft Corporation has recently acquired the domain name Xbone.com from its previous owner. Fusbile speculates that it must be a larger amount paid to the owner from Microsoft.
Major Nelson who is the Director of Programming at Xbox LIVE posted a message on NeoGAF saying that he don’t like the nickname Xbone for Xbox One.
“…disrespects the teams that have put in thousands of hours (already) into the development of the product. Sure, it’s cheeky but I don’t care for it myself.”
I guess Microsoft acquired the domain to keep it safe from competitors and fan boys from exploiting it against Xbox One.
