China has revealed 6th-generation 'stealthy' fighter

That's my take also.  I'm sure its radar cross-section is reduced just because of the lack of tail surfaces, but it doesn't look all that stealthy overall. 

Given the cranked wing leading edges and the overall aspect ratio I would surmise it's designed for super cruise at around Mach 2, but they have to do it the brute force way by adding an extra engine instead of with high-tech engine design.  That will give it the range and speed to be able to confront US forces in the Phillippine Sea out beyond Taiwan and the rest of the first island chain, but at the cost of endurance.

According to one of the designers, the third engine is primarily for power generation, which also says a lot about their engine technology.
