The way GNE are investing in new orders will be have all newish buses by the time 2017 arrives, this of course might be achieved with at least 160 new buses coming in to service over the next 2 years (said 2 years due to it being its 2014 in 2 days time!).
The only issue I can see with this is in 10 years everything will come up for renewal in one go!
