The rumored Yoga Tablet 3 will refresh the Yoga Tablet 2 with two configurations: An 8-inch model and a 10-inch model.
http://www.notebookcheck.net/Lenovo-Yoga-Tab-3-could-have-rotating-camera-and-20-hours-of-battery-life.148332.0.html
Main problems:
No windows version yet leaked, Qualcomm chip instead of Intel... Low res screen (1280x800).
Advantages:
Leaked price for 10 inch device around 130 usd.
So my hope is that it is low end of yoga tablet, not the main version.
