The Nintendo 3DS is about to enter Kagutsuchi. BlazBlue: Contiuum Shift II has been confirmed to appear on the unreleased handheld. There are no official details, though I think we can probably assume that it'll have 3D. BlazBlue's art in 3D is the stuff wet dreams are made of.
You may remember last year when it was revealed that BB:CSII would be released on the PSP as well. I wonder if it too will have a new game mode. Looks like the most happening spot for 2D fighting brilliance in 2011 is going to be on a handheld. There are no release details for this title.
