Poor odds on England but it is hard to see them losing.
A likely Eng team would be
Cook
Prior
KP
Trott
Shah
Collingwood
Mascheranas
Plunkett
Panesar
Sidebottom
Broad.

Seven of those have played plenty of 20/20 so should know whats what and of the four who haven't it is likely that KP will have little problem adapting.
A possible problem with that team is maybe a need for a specialist 20/20 slow bowler instead of Plunkett. The other problem is Collingwoods lack of experience both of captaincy and of 20/20 cricket in general. They should still be too strong though for the WIndies who have hardly played the game.
