Hi Wouter,
I think that T&Z will be available as an enhanced e-book sometime this
year, S&F will be an enhanced e-book next year, and Horn of Africa an
enhanced e-book late this year. All will have new plates, all will
have the sounds. Not too sure how much more use 2005 will be compared
to the original. S&F is already available for download for the old
addition, but does include the calls. (Available on ITunes)
Best for now
Brian
