The latest image (September 2017) indicated that since early 2017 a J-20A prototype has been fitted with two indigenous turbofan engines featuring stealth nozzles with saw tooth edges, suggesting the Chinese engine technology has become mature enough to finally have the Russian engines replaced.

I wonder if this means the WS-15 is still a ways off, since testing a new engine on the J-20 and then introducing a new engine into production would all take more time and effort than just sticking with AL-31s.

It IS still ways off. You may remember a member called "maya" (well known for his engine leaks) who said to fully complete the development of the WS-15 would take at least 10 yeard from the successful completion of high altitude 'core testing'. That was back in 2008/2009.
So by the most optimistic estimates, the final version of the WS-15 would be ready to be tested on the J-20 by 2019 but will takes more years for mass production.
IMHO 2025 (ish) would be a realistic date for the 1st WS-15 powered J-20B to enter service.
J-10 entered service around 2004 while the J-10B around 2013. Even if we reduce the J-20B development to 4 years that'll still be 2020+ timelines.
Of course remember Maya, and it seems a lot of what he told us when he was still around seems to have panned out more or less, so I can't say I'd be surprised if the WS-15 entered production no earlier than 2025. That said I personally suspect that the timeline for production might be much quicker than what we've experienced with the WS-10, assuming that their experience with prior projects count for *something*.

Then it is the WS-10B with a max thrust of 1400kN kgf (137 kN). The current WS-10 series cannot exceed 14000 kgf. From what I gathered. Only the WS-10IPE and WS-15 can do that.
137 kN is fairly low compared to the 147 kN of the 117 and especially the 156+ kN of the F119. Dry thrust and supercruise is the other mystery. But at least the WS-10B gives a high priority asset like the J-20 full independence.
Not a surprise, I have mentioned a while back that J20 will feature WS10x and there is guy trying run his mouth and said this makes no sense. I just replied back just wait n see, no need running the mouth, arguing for the sake of argument, trying to show people he's a smart ass and all that. So, what do you know?

Yep, they are fairly old and have been posted before in higher quality.
