They did drop Beatscape betweem X1 and X2, according to the web site product doc on included instruments. I don't happen to use it, but I was answering another thread and it had come up.
Mr Cook is correct - should you want to add anything back in from X1 that is not present in X2, just run a custom X1 install and you are all set.
Good luck, and welcome to X2.
