Cannibalise the remaining T1s after OSD to keep 10 (+ a couple spares/attrition reserves) flying 'til 2018 - for RAF Centenary fly past and farewell to the Reds.
No replacement thereafter - justification always quoted was "flying the flag", well there ain't nothing British no more! 9 or 10 top rank FJ peeps out of front line cockpits no longer sends right message for these days.
But of course, the RAF's got to make it to 2018 yet .....
.... you heard it here first!
