Sony Ericsson may have inadvertently leaked a new member of the Xperia family: The Xperia Acro. The company has yet to officially announce the phone, but it was spotted in the firm’s PC Companion software in Japan. We don’t see any specs listed in the leaked image, but that hasn’t stopped some blogs from speculating. XperiaBlog says the Acro sports a 4.2-inch display, an 8.1-megapixel camera, support for NFC, a DTV chip and a 1GHz Qualcomm Snapdragon processor. We would assume that the Acro will run Android 2.3 (Gingerbread) but again, nothing has been confirmed. Sony Ericsson may announce the Acro as soon as May or June of this year, but we wouldn’t hold our breath for a U.S. launch anytime soon. For now, it looks like its scheduled to hit Japan’s NTT DoCoMo and KDDI networks first.
