Crab,
I'm pretty certain UK PLC are going to lose 'a' helicopter fleet at least. However, what that is depends on what is politically acceptable. My personal money has been on green wildcat for some time (as you can spin it by putting them in a hangar and using them as a 'grey' spares pool). I'm surprised they're throwing both puma and wildcat into the mix but, as everyone says, you only save money by chopping a fleet, not by salami slicing.
