This is a huge surprise. I have already given up hope for J-31v2. I thought unless this project get some more money from the outside like the PLAAF, Chinese government or Pakistan that the project would be scuttled. I don't know if SAC got any outside funding to continue the program but in my opinion the Chinese government or the military should put money in the J-31 as this could be a good platform for export or even a potential future fighter for China herself.
It would be a huge bonus if its true that it uses a domestic engine.
