Alright, I gave it a better look!
A couple of observations:
Yep, Unreal Engine 4 again (probably with the PC being the main development platform again) and this looks barely better than Tekken 7 graphically... :/ Well, at least the beautiful fantasy designs and settings will clearly set it apart from Tekken 7 and make it imo look way more beautiful in that regard.
I liked Sophitia's design, Mitsurugi's however looked terrible, lol. He's young and handsome again though!
I think the character teased at the end was the new one, the one who is Kilik's arch rival in this and who uses dual weapons which he can combine to one.
