Here's the latest bit of footage from DJ Hero 2
which shows techno artist DeadMau5's in game avatar along with the re-mix of one of his songs. It's blended with Lady Gaga's Just Dance and doesn't really seem to feature much of the Deadmau5 song (Ghosts 'n Stuff).
I'm interested to see if the first game can build on the second or if it's doomed to the same fate as the original (which really wasn't that bad). I guess we'll find out this fall when it hits stores.
