Do you think Italy, Spain and Brazil will be fielding full strength sides in the upcoming Confederations Cup?

I hope the tournament will be reasonably exciting, certainly the Fifa Confederations Cup is worth having and Spain have an impressive undefeated run to defend. The trophy will look very nice next to the European Championship followed by the Fifa World Cup next year (only France have held all three trophies at the same time). Spain have a relatively easy group as well, consisting of South Africa (hosts), Iraq and New Zealand.
