Just noticed this Android TV Box on Geekbuying and to add to confusion they have named it Xiaomi Mi Box 3S. Most websites are calling it a Pro version or Enhanced White version.
US$72.99 when you apply the GKBAUG4 coupon code.
This apparently has more grunt than its predecessor as per the following: http://cavarii.blogspot.com.au/2016/03/xiaomi-unveils-mibox-3s-enhanced.html
Mod update: According to store rep, this is for the Mi Box 3 Pro/Xiaomi Mi Box 3 Enhanced Edition not Xiaomi Mi Box 3S.
Chinese version. Would advise against buying this.
