This could be one of many reasons why TN hasn't gave us many videos, they want the game polished more before dishing out more videos.
I think they've been pretty open about the progress of the game. They are willing to give us many different videos with graphical issues, but it still doesn't stop it from looking much better than Soulcalibur (I like this game) or Tekken.
One thing that I hope they fix is the stream of water on 'Lost Paradise.' To me the water does not look connected or meshed into the dirt at all. Road Rage is so incomplete they haven't shown us anymore of that stage. The first demo we didn't notice belly buttons. The Hiyami part of 'Unforgettable' appears to be incomplete.
Master has been pretty damn open to me, but he will not say a word about Hiyami. So who knows if we can explore that level or if it's just a tree we knock people into. They took time to dedicate a sign to it, so I hope the tree at least change seasons and Bankotsubo makes his noise when you smack someone into it.
I guess the point I'm trying to make is -- there isn't a lot of room for new videos. The game comes out in less than two months. It will likely not be delayed either as they are aiming at February like a deadline that can not be missed.
But like many I am hoping for that extra coat of polish before release.
