Which implies they'll be replacing the whole fleet.

(and I take it to mean that we'll be waiting a very long time for the
172s)

It seems to suggest that the 172s:

" will be to the London Overground standard, as you know, with lots and lots
of capacity, a much longer vehicle."

However most previous reports on the 172s for Goblin have said they'll have
a fairly normal internal layout, ie unlike the 378s, so that the Rosco will
have no trouble moving them on elsewhere eventually. As for 'much longer',
AFAICS the choices are 20m or 23m within normal UK gauge...
