New aircraft, new colours?

According to the local press, QinetiQ and the MoD have agreed to invest approximately £180m to modernise test aircrew training at Boscombe Down and air ranges in Wales and Scotland. The world-famous Empire Test Pilots’ School at Boscombe Down will receive a fleet of modern traing aircraft and an up-to-date syllabus for Test Aircrew Training.

Does anybody know which aircraft are in the running and will they all be painted in the traditional ETPS red white and blue colours?
