I think it might also be a good thing to note that not all classes have a Single Role and only that role. Most classes have a PRIMARY role, as well as a secondary role that just doesn't get specifically stated. This is similar to many of the monster entries we have seen that actually Do list their Primary and Secondary roles such as the Hobgoblin Warcaster who is a Level 3 Controller (Leader).
What we have seen to date would indicate th following.
ARCANE
Bard: Leader (Controller ?)
Swordmage: Defender (Striker ?)
Warlock: Striker (Controller)
Wizard: Controller (Striker)
DIVINE
Cleric: Leader (Striker)
Paladin: Defender (Leader)
MARTIAL
Fighter: Defender (Striker)
Ranger: Striker (Defender)
Rogue: Striker (Controller ?)
Warlord: Leader (Defender)
Along these lines there is still room for classes that fill other combinations such as a Divine Controller / Striker as an example.
