Well, there clearly is a model, and supposedly this was commissioned by Dalian Shipyard to plans they provided. So there is that.
I would correct you as saying "there is a model".
That is that.
We do not know definitively who commissioned it nor do we know what it is meant to depict. For example, let's say it is from Dalian and is meant to be "CVN-20". Does that mean we can say there is no CVN-19, and that 19 has to be CV-19 instead?
Also, that model isn't exactly new. We saw it some time ago, here:
We are off topic again, this is a PLAN aircraft carrier 004 thread. Please go back to the track.

And all this in context of us not having any reliable rumours associated with this picture of the model.
So no, I don't think this picture or article changes anything at this stage.
People should remember that for projects with great uncertainty (such as the future of Chinese carriers), the single best category of sources is credible rumours from the Chinese PLA watching side from individuals with a good track record.
