Lenovo ThinkPad X230 to the ThinkPad X240 delivery date of January 8, 2015?

As I have written previously, I am a ThinkPad user. I currently have the ThinkPad x230 and I eagerly await my ThinkPad X240.

However, I am concerned as I constantly go to the Lenovo.COM website and go to customize the ThinkPad X240 and find many of the customization’s to change from time to time. Moreover, I am also questioning the ship date. It states on the website, estimated ship date 2015/01/01 and estimated delivery date 2015/01/08.

Ship date states 2015/01/01

I have tried to call them but they are very busy. Hopefully, I will find out soon. But in any event, I have customized my ThinkPad X240 with 8GB PC3-12800 DDR3L (1 DIMM), now on the website, it is only allowing you to configure 4 GB total memory. Not realy sure what the problem is?

Only Memory Size coming up in customization is 4 GB, But I ordered 8GB

For Example: the configuration I have ordered is as follows
