FA.2 v type 45?

Since a few topics are now running about the retirement of the sea harrier in the next few years, I thought I would ask this:
Will the type 45 destroyer truely be able to fill the Air defence gap left by the sea harrier until JSF arrives?

this is from the Ministry of Defence website:
