That guy has no PLAN inside information, however he is a close follower of PLA. I find his list of missiles as completely useless information, since there are probably at least 20 combinations the PLAN will use depending on the mission context.
There were some rumors of ASBM/hypersonic weapon that will be equipped on later 055 variants, first mentioned by Du Wenlong, a "military expert" that talks about military stuff on TV. His credibility is average, probably better than Zhang Zhaozhong (the one who made all the worst possible Iraq War predictions, like US will be mired in guerrilla warfare and achieve little to hurt Saddam's regime). Then Pop3, a very credible big shrimp completely dismissed Du. After that, a military commentator that writes blog posts on PLA, whose family had fairly close connections with PLAN, came out and said the big shrimp have left the navy for too long and were not aware of the most recent advancements. He claims to have boarded the launched 055, and was present when a 052D captain expressed his jealousy of the 055 for "new anti ship weapons". He personally do not believe the weapon to be YJ-18, which is already equipped on 052D. He also mentioned the length of the VLS cells are different on any single ship, with the later 055 variants having a higher proportion of 9m x 0.85m cells than shorter cells.
Normally i would place pop3 as the most reliable source, but in light of the recent Guanghua award nominations leak, I find naval hypersonic weapons highly plausible in the 2020s, as a complement to the lack of strike power of PLAN from too few carriers in service.
