I figured it out.. the sparse'ness observed so far in this game reminds me of Sengoku Cannon: Sengoku Ace Episode III.
Capcom has taken animation to the next level and it is a 2D approach. The new KOF looks nice but it certainly lacks what SFIV has with the subtlety and details, Capcom really succeeded.
If traditional 3D games took the amount of attention and care that SFIV does then they can also rise to the "next level", it is easy for SFIV because they always know where the camera is going to be... so they can animate for max usage of that side view.
Really, imagine FPS's that have the enemies telegraph their every move by subtle body motion, current games do not do that at all, ok RE5 does a bit from what I played, and bosses in games tend to, but no developer has worked that type of thinking into the basics. You're going to see it happen at some point, some dev is going to do it, and that will be it, the bar will be raised and people will be like "oh shit what". It will also lead to making slower-paced action retain challenging difficulty (particularly FPS genre), it will work great with analog sticks.
anyway, all personal opinion... this SFIV KOF discussion should probably go to another thread though, we already got enough sidetracked discussion of loli's going on here.
