Apparently the Metrolink Solars are going on the Waggonway in September, so there is still another 2 months, so plenty of time for new build citaros to come in.
It was February I believe when the news broke out about the new buses. So between then and September is 6 Months and were probs ordered a few weeks before that so make that 7 months, 8 months at the most. Rough guessing from memory there. I'd say 7 months is plently of time.
If you think about it the Streetlites were announced at the same time and they are due sortly also, so i'd say the Citaros might be New Builds
