Looks like this is like a version of the TSP with less outputs and no Dave Smith filter kinda similar to the MPC Live/MPC X setup for Akai?
If the software editor can swap project files between the two I'm guessing they'll be based on the same firmware and features and looking at the manual for the DJS it looks as though Pioneer have tried to address a lot of the requests to date.
I'm really looking forward to the 1.4 update..
