Whilst abolishing the RAF is probably not going to happen, the RAF have opened themselves up for some serious re-organisation by presiding over several high-profile procurement fiascos - eg Nimrod, Typhoon, Chinook Mk3 - which will be absorbing more funds for some time to come.
I can't find the source now, but I may be correct also in writing that the RAF are more top-heavy with senior officers than the other services.
