There's a new footage video up. It shows what seems to be an early version of one of the specific Rogue levels (albeit still played with Bishop in this proto).

The ninja-themed level from the other video was being assigned to Wolverine in the final version anyway.

PS: Fans of Jesper Kyd should recognize this music.
