There will be changes to selected Adelaide Metro services from 24 July - see http://www.adelaidemetro.com.au/timetable-changes-24-july-2011 (http://www.adelaidemetro.com.au/timetable-changes-24-july-2011) for details. Apart from the introduction of regular bus routes to Gawler, one of the biggest changes is the introduction of a new printed timetable format. Would be interested to hear what y'all think!
Do they now have network maps?
Almost certainly; MTT, Trans Adelaide and now Adelaide Metro have been pretty good over the years in having network maps available. They usually charge for them (like ACTION used to do).
The new combined network map, which replaces previous Metroguides, is now available at http://www.adelaidemetro.com.au/routes/metroguide (http://www.adelaidemetro.com.au/routes/metroguide).
