Releasing on multiple platforms, along with Kojima's statement of wanting to cater more for western audiences in his games AND the fact that Kojima isn't directing Rising, suggests to me that the game will have shorter cut-scenes, more action and less of a Metal Gear style stealth or story.
From that video, it looks as though the game is going to be like Streets of Rage in 3D with a ninja sword!
"Cut at will"
"Cut what you will"
It was almost like a tech demo for a game engine, showing off the environment damage that Raidens sword can inflict.
I just cant get excited for this game.
