Taking into account that WS-10 only has 12500 kg of thrust (info revealed at zhuhai), what are the chances that ws-15 equals or gets near the latest russian engines (15000 kg) ? IMO little chance of that. Most probably Ws-15 is based on WS-10. What is the latest news about it?
Chinese Engine Development

It isn't. You've been here a while, WS-10 and WS-15 are being developed by separate institutes.
according to tphuang, ws-10 and ws-15 are developed by the same company, SAERI (shenyang aircraft engine research institute...i guess).
I've been getting conflicting data about WS-15 development, some say it's Institute 606 (Shenyang) while others say it's Guizhou Liyang, so it would be great if someone could really confirm what's actually the case.

WS-15 has no relation to WS-10. You can tell because they had to come up with and test the core of WS-15, which they wouldn't have to do if WS-15 has heritage with WS-10.
WS-10 can trace some of its origin to CFM56; WS-15 is completely a new design with a new core engine.
I was surprised to see WS-15 project listed in recent aero engine summit brochure under "Chengdu Aero Engine".
CHINA AEROSPACE PROPULSION TECHNOLOGY SUMMIT
New Aerospace Power for the Future
19th & 20th June, 2012 Shanghai, China
This summit was attended by chief engineers and executives of world wide manufacturers (AVIC Xi'an AE, COMAC, GE, Pratt and Whitney...). Interesting key note speech was given on "Work division and cooperation of China aero engine development".
The main problem for helicopters as well as transport aircraft and bombers is the availability of suitable engines.

Any link to the summit speeches and presentations?
hmm, I don't think AVIC1 actually works that way. How the research institute and the aeroengine company interact is still pretty mysterious to me. So, I think you are getting the wrong impression here. I believe the aeroengine companies like Xi'an AE, Shengyang Liming, Guizhou Liyang and Chengfa do the actual testing and production of the aircraft. I think their responsibilities is as follows:
XAE: WS-9, WS-15, WS-20
Liming: WS-10, QC-185 (QC-280???)
Liyang: WP-13, WS-13
Chengfa: WS-18
If Maya was here, he'd be able to do so much better job of explaining it than me.
The designed requirement for FWS-10 was 12.5 ton and 13.2 ton for FWS-10A I think. So, the mass produced units more or less reached it for FWS-10. For FWS-15, I believe the design is to have T/W ratio fo 10 and the max thrust with afterburner is 16.5 ton. FWS-10 and FWS-15 are two different generations of engine. From what I hear, the development for it is going pretty well. But as with all other Chinese engine project, until you see the production going smoothly, it is what it is.
But regardless, the comment "what are the chances that ws-15 equals or gets near the latest russian engines (15000 kg) ? IMO little chance of tha" is a wrong way to look at things. The latest Russian engines are basically upgrades to AL-31F series. WS-15 will use a whole new core, new material and technology not currently used on WS-10.
Also, you have to consider that WS-10 was basically the first major aircraft engine project China embarked on. They certainly made mistakes in the process, which will hopefully be not repeated on WS-12/13/15/20. Xi'an AE has also been better with production than Liming in the past. I'm cautiously optimistic that WS-15 project will experience less pain than WS-10.
