One interesting thread on baidu forums: http://tieba.baidu.com/p/2908094183
The main post is by someone connected with Huawei's theme development team and talks about their current situation and future progress. Seems like they are going to pay more attention to detail and bring quality themes, but on the other hand some talk about payment system is also in the works. He also mentioned about EMUI 3.0, although im not sure if it is a typo.
Also look at the 11th post on that thread, where a person posted a screenshot of his notification panel. Notice that they have 4 rows of shortcuts with new shortcut keys, while the Emui2.3 beta we using only has 3 rows of shortcuts.
