I don't actually think it will be the Red Arrows though as I think come the next set of changes, it'll get dropped to every 12 minutes with 6001 and 6004 acting as spares or working the 921 (if not interworked) and although the argument stands that the Galleries - Newcastle section warrants a 10 minute frequency, so did the 56 warrant such frequency 'at times' but if the frequency was dropped and a PVR of 12 was to be used, then the reliability of the service would also improve meaning more buses and less chance of passengers having to stand.

However, given the routes that the Streetdeck has been trialed on, here's my two predictions:
____________________________________________________________________________________________________________________
One:
- 14 + 2(spare) Wright Streetdecks for Hexham / Riverside for TEN services 10/10A/10B.
- 6071 to 6077 transfer to Crook for Pronto service X21.
- 6078 to 6081 remain at Riverside but are branded for Red Kite 47 to provide commonality with the 45/46.
- 6082 to 6083 move to Percy Main with Cobalt Clipper vinyls and branding (no repaint) to allow the PVR of the Cobalt Clipper to increase to 17 (still be 19 with 2x 'red sheds' thrown in at peak times but the extra vehicle would improve the flow particularly during the afternoons).
- 6084(T) remains at Riverside as a dedicated TTX spare.
- 6116 and 6117 go back to their intended roles as spare vehicles.
- 6084 becomes a dedicated TTX spare.
- 6118 and 6119 become corporate spares at Chester Le Street with 6120 and 6121 also moving but acting as the extra 2x vehicles on the Angel fulfilling the PVR requirement of Angel service 21. The latter two could be fitted with NSA's or refurbished to the exact same standards as the B5s or even all of this including GKN mods. (note that they already have Wi-Fi).

- The best out of 3941,42,62,63,64,65; then provide where needed in the following order based on route and vehicle demands:
 
 Crook (spare), Riverside (spare), Percy Main (DFDS x2), wherever needed (spare x2)

Two:
- 14 + 2(spare) Wright Streetdecks for Hexham / Riverside for TEN services 10/10A/10B.
- 16 (or 17) +2(spare) Wright Streetdecks for Percy Main for Cobalt Clipper service 309/310/X39.
- 6101 to 6103, 6105 to 6116 and 6071 to 6076 transfer to Deptford for Prince Bishops service 20. (PVR 20)
- 6117 transfers to Deptford and acts as a spare for Prince Bishops service 20 and the Fab 56 alongside 6099 and 6100 covering a PVR of 32 vehicles (1 spare B9 for every 8x branded B9s). Note that the 4th spare B9 would result in 6104 (GKN) also transferring and being rebranded for the Fab 56 and one of the NON GKN vehicles on there at present, being repainted  into corporate livery as a spare.
- 6077 to 6083 transfer to Crook for Pronto service X21. (PVR 7)
- 6084(T) remains at Riverside as a dedicated TTX spare.

- The best out of 3941,42,62,63,64,65; then provide where needed in the following order based on route and vehicle demands:
 
 Crook (spare), Riverside (spare), Percy Main (DFDS x2), wherever needed (spare x2)
