EDIT: It is likely that they will wait until sufficient are available until service 3 is fully operated by GAS buses, rather than just a couple.
Of the 10 recently delivered, 6 have been registered, but the last four (28024 - 28027) still haven't. So another three need to be available to fully convert the service.
It's also possible that they've got some issues on the older ones that require looking at and whilst Scania are there it's a good chance to get them in especially now they've got all of the new ones as extra buses to play with.
There's a good chance the new ones will go out during the course of the day too, rather than just being allocated from the start of the day. I remember taking 22015 on its maiden voyage on Teesside as they gave me it as a changeover (at the depot gates on a 13).
