Prior to the 2011 flood events, I understand that the timetables would have been likely implemented March/April this year. The flood events, particularly the constant rain did cause some issues with a number of the suburban units.
This possibly the reason why the date is now 6th June 2011.
I suppose on the bright side there is a bit more time to re-align the buses with the new timetables in a more effective manner.
Hopefully the final timetables might be publicly available next week.
As there is still around 3 months before the new Ipswich - Caboolture timetables (which includes Richlands) I think QR/TransLink should fix the botched interim Richlands timetable that has shuttle trains on the branch missing connections by a minute or so. Hopeless, it has been pointed out privately a number of times and it is time to go public in an attempt to sort it.
