This is apparently "Mystery Game X" that Jane Jensen and Pinkerton Road Studios have been teasing since their Kickstarter. The backgrounds look amazing and the remade theme song is quite good as well.

Indeed. Looking forward to it.
Not a fan of Phoenix Online Studios, but I did very much enjoy the original Gabriel Knight.
It will be interesting to see if the animation looks the same as what we saw in the Moebius trailer from them.
