yes, there are big plans for big changes:

The current development version of hexbin will use  grid
graphics which allows "everything" in principle,
but the user utility functions might well be lacking initially
-- and you willl have t ouse grid (or lattice) graphics;
no par(.), no traditional graphics...
Also, the result of hexbin() will be an S4 object instead of a list.

There is some unfinished discussion going on, 
if the old version of hexbin should be kept available in package
"hexbin0" -- for those of you who can't update quickly to the
new API to hexbin graphics.
