Actually it won't include compiz either. Here is an excerpt from the Ubuntu news letter on this topic.
=== Feisty will not include Beryl or Compiz ===
According to Matt Zimmerman, "Ubuntu 7.04 will preserve the status quo with respect to proprietary video drivers. As in previous releases, these drivers will be provided for the convenience of users who choose to use them, but they will not be activated by default." This decision was made at a Technical Board meeting which decided Compiz and Beryl were not stable enough to be shipped. Once again, the discussion on the mailing list says "However, some of the relevant software necessary to implement this proposal is not yet considered mature enough to deploy in the default Ubuntu configuration." Therefore, composite will not enabled by default in Feisty but the Technical Board has made in clear that they believe this technology will be implemented in the near future.
