I think it's also fair to speculate that we'll be getting a new map for the train system with the May 8th timetable change.
Definitely a strong possibility. "It’s the first in a series of new public transport maps that will make travel easier for passengers." as on the Yarra Trams website. Maybe they will bring Harry Beck to Melbourne! I wish.
EDIT: Actually based on the new timetables currently uploaded onto destinationbetter, maybe this will come a bit later.
Like the new map a lot, especially that it makes roads with multiple routes a lot easier to read, however longer routes are a bit harder to track. Brings out the irony at Box Hill as well, tram stop in Zone 1, train station in Zone 2.
Also since the October 2010 Metro timetable and now with this, City Saver will most definitely see the grave together with Metcard.
