I think that the expectations were too high before the reveal.
Capabilities wise it will give PLA an attack heli the capability of taking off from mainland air bases, fly across the strait, and loiter for a long time for close in fire support. The significance can’t be understated.
My feeling is that the rumour about the coaxial attack helicopter raised expectations a little, but I think everyone should have also been skeptical about that rumour being for attack helicopter intended for short term procurement.
Let's put it this way -- even the US does not have a heavy attack helicopter under development pursuing an unconventional/exotic configuration like coaxial +/- pusher prop, and US helicopter technology and industry is ahead of everyone else.
The idea that the PLA would pursue a heavy attack heli with such a configuration intended for service should have run some alarm bells.
Now, it is still possible that we will see an attack helicopter in some form with a coaxial+pusher prop configuration in the near future, but I personally do not expect it to be intended for procurement in the near term, but perhaps more as a technology demonstrator or something less ambitious like an armed scout helicopter.
