Not keeping all, Just a few I believe. Unless plans have changed.
Last I heard, was that they were all staying. No idea how accurate that is.
Have you heard where the 91's are supposed to be going (if VTEC aren't keeping them)?
There are 65 Class 800/801's being built for use on the ECML (23 that are dual-mode with 10 that are five-car sets)
According to wiki, there are 16 Class 43 sets and 31 Class 91's allocated to VTEC currently.
