The MetroCity pictured is certainly one of the existing fleet, and there's a CardiBach vehicle next to it so maybe they are counting the CardiBach as well as the 4 TrawsCymru MetroCities.http://www.tivysideadvertiser.co.uk/news/13370925.New_fleet_of_buses__vital_to_the_local_community_/
5 new buses, or are they mentioning the '4' already in use?
The article also says: "This latest fleet takes the total of new vehicles introduced across Wales to 15." I can't figure out where the value 15 comes from. If by 'new' they mean 2015 registrations of TrawsCymru vehicles then surely it is only 8 (4 MetroCities for T5 and 4 Envrios for T3), or if there really is another 5 new buses coming to T5 in addition to the 4 MetroCities then 13. New buses purchased for TrawsCymru services since its inception is 14 (6 Tempos + 4 MetroCities + 4 Enviros). In that case its only one short so perhaps YR14HLU was new for the T3? Or maybe a fifth MetroCity has been ordered for the T5? The overall size of the TrawsCymru fleet must be quite large now, there are at least 12 vehicles in the T5 livery alone.
