Sony made huge strides with its line of Android smartphones over the past year, but the company may be shifting some of its focus to Windows Phone in the near future. In an interview with TechRadar, Sony Mobile Europe chief Pierre Perron said he's wary of being a one OS company, adding that the Japanese titan is in regular talks with Microsoft.

"We don't want to be a single OS manufacturer, I don't think it's a viable position in the long term," Perron said.

While Sony is apparently more interested in developing hardware for Windows 8.1, Microsoft may be leveraging its desktop OS to gain support for Windows Phone. According to Perron, Sony is open to the possibility, but has questions about the viability of the platform itself as well as how it can be modified to give the company an advantage over the competition.

Microsoft and Sony were once mobile partners in a relationship that peaked with the Xperia X1, a smartphone that launched in 2008 running the now-obsolete Windows Mobile OS. The Xperia X2 saw a shaky launch a year later, before Sony switched its mobile focus entirely to Android with the Xperia X10.

Whether Sony will take a chance on Windows Phone is unclear, and while Microsoft's mobile OS continues to grow in market share not everyone at the Japanese company shares Perron's enthusiasm. According to Mobile CEO Kunimasa Suzuki, Sony currently has no concrete plans to release a Windows Phone device. Still, anything's possible so long as talks are ongoing.
