According to Pocket Now these “designs are for East Asian versions of Windows Phone. They were created by a Microsoft User Experience Designer for the next version of Windows Phone.”
Just by looking at the design you can infer that folders may be coming and that you will also have more freedom when it comes to tile size.
Here is an example of what your tile size choices may look like in use on a Windows Phone.
Naturally, all of these things are just ideas now and are subject to change…however the more choices that I have in customizing my phone the better. Feel free to leave your thoughts in the comments!
