For Spring 2013, the plan is that MAN will have an extra 2 based aircraft. One of which was initially ear marked for 2012 which is testament to the fact that things change.
Elsewhere in the Orange Kingdom. New recaro seats being trialled in the hangar will be on new aircraft deliveries from April 2013 provided an issue with CAA certification is sorted out. New seat covers and carpets being looked into.
Also a one off UNICEF aircraft is being planned along with (apparently) a livery refresh. I wouldn't expect anything radical from the latter but interesting nonetheless.
