Yes I agree with you on most of your points, although Wattisham could also take Helicopters.
As for moving training it wouldn't all go to Cosford, some enginnering training could be moved to St Athan, whilst other units could go to Cranwell.
As for the DLO bases it has been made clear that large cuts will go ahead and also that training establishments face amalgamation
As for Yeovilton it would make a good JHC base, but at present with further Naval cuts and the scrapping of much of the FAA's roles including Sea Harrier, it is looking increasingly at risk.
Finally the Review was not full announced because Geoff Hoon is hoping to get moved in the upcoming cabinet reshuffle as he has made it clear that he is unhappy at the MoD.
Geoff has therefore left his predessor to be the bearer of bad news.
