From the launch titles we learnt that duplicating the screen on the Gamepad takes 10 lines of code. Changing the splitcreen to full screen on both the TV and Gamepad would require; what, 2-3 days? Porting the mode itself could be the time consuming part, but they've already done that for the main game.
Don't really care. The game was never on my radar, and neither are any of Ubisoft's future titles. The only current third party game that could be interesting for me is Sonic, and I didn't even enjoy playing its predecessor on the Wii.
PS: BB is awesome :)
