Thanks. They would be starting at 3rd level, so that would work. Is there a place where I can find brief descriptions of each of the new classes?
The articles on the D&D website give the "opening" parts of the previews, basically the part explaining what a character has for HP, surges, defenses, proficiencies, recommended stats, etc ... The powers are only shown if you also have the DDI subscription.
Made even simpler:
BARD - Arcane Leader, CHA based, secondary INT (ranged) or CON (melee), shows 10 levels of the secondary INT build. Keeps some of it's "jack of all trades" reputation by being able to take multiple multiclass feats.
Sorceror - Arcane Striker, CHA based, secondary DEX (wild) or STR (dragon), has 3 levels shown. Gets a fixed damage boost (based on secondary stat), instead of extra damage dice.
Avenger - Divine Striker, WIS based, secondary DEX or INT (?), only some info is available, such as from the Penny Arcade podcast series, and the pregen character. Instead of extra damage, it has an increased accuracy, being able to roll twice on melee attacks against their chosen foe (under the right circumstances).
Invoker - Divine Controller, WIS based, secondary CON or INT, first 3 levels are shown. Hard to find a "theme" like with the other ones, although it does have some angel summoning involved (no word on BMX banditry).
Shaman - Primal Leader, WIS based, secondary CON or INT, first 3 levels are shown. Has a spirit companion that is a bit like a summonable animal companion, which is connected to some of the powers.
Druid - Primal Controller, WIS based, secondary CON or DEX, first 3 levels are shown. Able to wild shape to switch between humanoid ranged caster mode and melee beast form.
Warden - Primal Defender, STR based, secondary CON or WIS, first 3 levels are shown. Dailies involve polymorphs that include an attack that can be used later [compared to the barbarian rage that starts with the attack]
Barbarian - Primal Striker, STR based, secondary CON or CHA, all 30 levels shown, but seems to have been slightly altered (based on pregens), and the CON based 'half' is shown. Daily "rages" work like stances (in addition to attack powers)
