The new Pietra di Luna guide for Sardinia will be published in Italian at the start of 2010. It will contain ONLY crags (falesie), and unlike the last edition (updated to 2002) it'll have all the island's crags, not just the most important ones, for a total of 120 crags and 3600 SINGLE PITCH SPORT routes. It won't include multi-pitch routes and boulders (see current Pietra di Luna + various updates, see
http://www.ukclimbing.com/forums/t.php?t=345228&v=1#x5069568 before I discovered UKB, sorry guys) nor trad routes (CAI 1997 guide + various updates).
The English translation will be finished around the start of March (I shall be doing it) and the guide in English will then be printed.
In the meantime, the map guides to Cala Gonone, Ogliastra where we live see
http://www.cordee.co.uk/CCE357.php and Northern Sardinia are pretty up-to-date and well worth €14 each.
