I believe that's the 2GB Ram version, I'll wait for the 3GB Ram version. Alternatively wait for the more compact Jiayu S4, which be out at some point within the first half of 2015.
Xiaomi Mi Note looks very interesting. Especially if priced at €450/£340. The Jiayu S4 you can keep. I don't trust Mediatek SOCs, but when they use Qualcomm it shows they're interested in quality.
