WPCentral posted a story that Microsoft has revised their chassis specification for low-end, cost-conscious devices.

During the Microsoft Conference 2011 in Shinagawa Japan, a slide was presented (as seen above) that details the new specifications. 
Tezawaly from the site NanaPho.jp was kind enough to translate the new specifications:

Capacitive Touch Panel- 4 points or over multi-touch
Sensors - A-GPS, Accelometer, Compass, Proximity
Camera -3MP or over
Connector - MicroUSB, 3.5mm jack
Storage - 2GB or over
CPU - ?

We doubt we'll see any such budget phones here in the US, but it is interesting to see Microsoft really try to go after all ends of the market.
