From what I understand Bus Eireann is still in discussions to see if they can afford a small number of new coaches for tours next year , 12 - 20 is the number being thrown about.
I would imagine that if an order does go ahead they will not be ordering premium coaches , whoever puts in the most attractive tender in financial terms will get the order , this will most likely mean either more LC's or Volvo's or Scania's with the cheapest bodywork possible.
