Just yesterday, the Sony Xperia feat. Hatsune homepage was mysteriously revived for unknown reasons. The website serves as the portal for Sony’s previous Xperia feat. Hatsune Miku phone, released in 2013.
The website was previously hosted at dx39.net, but it seems that domain was snatched by a domain squatter. Instead of buying back the domain, the website was revived at dx39.jp. The reason for the revival is unknown. Perhaps Sony simply realized they forgot to pay the domain bill. They could also be planning another music remix collab. Or they just might be planning a special announcement (a new phone, perhaps?).
The 2 year contacts for the Miku Xperia phones expire this month, so it’s entirely possible for a successor phone to be announced. The website revival comes not too long after the supposed Xperia Z5 Compact Miku phone rumor, although that particular rumor was stated as false by Crypton Future Media (Hatsune Miku’s creators). If anything special is indeed planned, we might hear something soon.
EDIT: Sony just made an official tweet via the dx39 twitter announcing that the special content delivery services for the Miku Xperia will end on September 18th. It’s very interesting that Sony would revive the Miku Xperia site, but then announce the end of content delivery services for the phone the next day.
