Well, the A5 appears to be sold out on all models on JD.com so it may be a while yet before I get my phone from the CECT Shop.
However, from looking at the Hisense A5 on JD.com, it appears that they will be coming out with a model that has 6 GB of RAM with either 64 GB or 128 GB of onboard storage.

Guess I should have waited just that wee bit longer before making a purchase.
