This looks very promising. I really hope they do this game right. I haven't ever beaten a Ninja Gaiden, since I never played the MS or Sony console versions, and the NES versions are amazingly hard.
It's good to see a developer using the DS in unique ways, hopefully the touch screen interface feels good. I'm intrigued by their choice to go with the Book style positioning. Seems to make sense based on the camera angle positioning (more helpful to see ahead of you than on either side of you).
Fall of this year! Sweet. What a great lineup for this next fall/winter for Nintendo.
