Arriva North West and Wales upcoming Fleet movements

RE: Arriva North West and Wales upcoming Fleet movements
Does Winsford still have 908 and/or 894 in service? I would have expected these to be earmarked for imminent withdrawal given their age. (OK, 894 isn't actually as X-registered as it looks, but it's still 15 years old this month.)

On a separate note, I wonder why the fleet numbering for new double deckers is suddenly all over the place? First, the seemingly illogical omission of numbers 4693-4799 prior to the allocation of 4800-4850, which are basically just a restyled and updated version of 4492-4535; now it seems a completely new series (10xx) is being started for the new ADLs.

Hybrids and conventional diesel-epicyclics, premium and regular specification vehicles, different manufacturers, have all previously been numbered sequentially in one standard series, so I don't see what's fundamentally new about these vehicles enough to start a new series.
