Combat looked faster in the previous trailer (could be because this is early game though) and I don't know what's up with the voice acting (especially for the companion) but it feels slow and awkward to me at points.
The knight moves seem a lot like the eikonic feats of Final Fantasy XVI which, coupled with the Titan-esque scale of the boss they showed at the end, does make it another likely point of inspiration.
Still interested in what I'm seeing here, it looks really cool.
