The optimist in me wants to say, "Wow, another breakthrough for the TLM!"
The pessimist (realist?) in me wants to say, "Hey look, they're reeling in the society for the final push to force the New Mass and the Latin Mass to be celebrated as equals... and later seeing TLM barred from the chapels with the NO in its place..."
Another thing that disturbs me is that the Society was not told ahead of the announcement. Of course, they could always be masking their knowledge of it anyway.
On one hand we could be witnessing a powerful moment of grace sent from Heaven while on the other hand this could be a stratagem straight from Hell. Perhaps the Devil's plans will work against him in the long run, who knows? All we have right now is the Mass of all time while we wait for the eclipse to pass us over.
