are we going to see 3 different formations for the 3 games?

4-5-1 v france (carroll, downing and milner starting)
4-4-2 v sweden (dropping carroll, downing and milner for chamberlain, defoe and welbeck)
4-4-1-1 v ukraine (dropping defoe, welbeck and chamberlain for rooney, and 2 of milner, downing and walcott)

what does everyone think will happen?

I think it'll be 4-4-1-1 for the French game - Young behind Welbeck with Downing and Milner on the wings. Thereafter, it'll be 4-4-2 for every game with Young on the left, Milner on the right and Carroll and Welbeck up front. When Ukraine rolls around, Carroll will be dropped for Rooney.

I'd pretty much echo Duty281 there
