IMHO, they'll keep the door open to publishing tweets - i.e.: they want people to be able to tweet from their iphones, from websites, etc. But... they'll close of (1) social network type stuff (your follower and following lists), and (2) close out third party's ability to consume tweets - i.e.: viewing my tweets, or other's, somewhere other than Twitter. i.e.: the API will be for publishing to Twitter, not consuming from.
