From NeoGaf:
The article is fairly general and focused on the change in setting and what not, there is a lot of "we can't talk about that yet". I also haven't sat down and read it yet, just skimming.
-1st person, cell shaded, like I said, similar to XIII,
-going for teen rating so, "The gore just doesn't fit for us and what we're trying to do"
-No multiplayer
-exclusively Wii Motion Plus
-talk of dual wielding Gun and sword but nothing definitive
So Red Steel 2 w/MotionPlus bundle is looking likely as MotionPlus is NEEDED for this title. Also no multiplayer, the team wanted to focus on the single player component and they actually completely changed direction when MotionPlus was first revealed.
Most Interesting part I think is the possibility for dual wielding gun and sword :D
