Does Sorin's Vengeance hit Planeswalkers?

I think it does because says 'deals 10 damage to target player' rather than 'target player loses 10 life.'

Correct. You have to target the player, but can redirect the damage to the planeswalker just like with a Lightning Bolt.

i dont see why you couldn't, it's worded just like a Bolt would be, Target player takes X damage. Then you gain 10 life.
