They're all there except the Ocean/Illustrious permutation:-
Ark Royal to be gone by April 2011
4 x Type 22 to be gone by April 2011
1 x Bay Class to be gone by March 2012
1 x Albion Class to be mothballed by March 2012
5,000 RN pers to be gone by April 2015
SDSR notes that a single LPH (type) ship will be kept in service. It doesn't say for how long and it states that a decision is to be made whether it will be Ocean or Illustrious. The only review/decisions is/are which of the two hulls will be disposed of and whether any will remain after 2015.
