Another Medfield phone, the Lenovo K800 has been released this month as well, though apparently only in China. It's similar to the Xolo. but a bit chunkier with a bigger 720p screen.

There are finally some videos up on Youtube:
Unboxing & hands on (in Chinese)
Gameplay (with WiDi connection to big screen I think)

I really wonder how well Windows/Wine/x86 Linux applications and games would run on these devices.
