I've tried working allocations out but impossible and will wait until revealed. But can work out the E400MMCs from an educated guess. They'll certainly be a big help in terms of improving reliability and reducing lost mileage on the X21(?) particularly with the West Auckland extension. And the extra oooomph will help with the steeper parts of the X70/X71 too.
I agree on the X1 getting at least 15 of the new Streetdecks, with 1 of those Streetdecks becoming spare so depot standardisation can take place, although i do like your idea of the E400's on the X21, i don't think they'll repaint the Streetdecks in to the Green version, unless they swap the colours around.. so Blue for the X30 etc and Green for the X21 but i very much doubt that'll happen.
Don't think that'll happen anytime soon, be when the buses start to arrive next month, when everything gets revealed.
