There has been some out-of-list discussion about this, and some work is
being done. There's a PP based tuple implementation (mostly written by
Joel) in Spirit's CVS that conforms to the Tuple speicification in the TR.
(Note that the current Boost.Tuples is not one-to-one what was accepted
into the TR. Most notably, the cons-list interface was not standardized.)

The PP based tuples are not complete yet, and what the iteration interface
will be is still undecided.
