More Arriva London cascades?

RE: More Arriva London cascades?
I reckon there will still be a few more, but maybe not as many as in the past... Rhyl and Bangor have Y plate deckers which could be replaced this year since all the other 2001 stock seems to be going, also a lot of the current deckers around the North West are going to Southern Counties, so surely these will all need replacing at some point (presumably some of it was done by the hybrids but I doubt they have replaced everything)
