US lawmakers have signaled that nothing created after 1928 will ever become public domain. Why 1928? That is the copyright date for Mickey Mouse and he is worth too much money to let become public domain.
Pedantic here - while Mickey Mouse was created in 1928, the cut-off for public domain works is 1923. Also there was a long period of time where works needed to be registered (and re-registered) so there are plenty of works that have fallen into the public domain since 1923 (Night of the Living Dead being a prominent example).
You are exactly right and Congress "fixed" that. Currently no copyrights will expire until at least 2019. Anyone want to bet Congress passes another copyright law before then that extends copyright terms?
