The first Embraer 170 routes are already known. From Oct 23 it will operate a 4th daily BNE-CBR-BNE (afternoon) and a new BNE-CNS-BNE flight (morning).
As the 2nd and 3rd aircraft come in more frequencies are added. No new routes announced as yet (watch this space) - I believe nothing new in terms of routes until the new year?
Other forums have listed the ERJ routes and schedules in some detail
