Stagecoach Manchester

RE: Stagecoach Manchester and Wigan
I've got to be honest and say I've skimmed very loosely over comments regarding the B10M running day in Manchester next month, however, a comment on another forum tonight (that sadly for some reason I'm unable to post or respond to), suggests both 20982 and 20983 are both set to be withdrawn sometime around the running day, so if they are to be withdrawn/retired permanently what is set to replace them on the 700 school service?

One theory is that 33866 could be used or possibly one of the Enviro200's or maybe one of the evolutions.
Although the Sunday AZ operated 202's do mainly see Solos occasionally Enviro200's are used and do just fit over the bridge although I'm told they perfer not to use them 'just in case'.

Apologies if it's already been discussed on here.
