8 classes is a bit smaller than standard, but... Some of the basic ones are a bit boring. Barbarians, for instance, don't have much else to do than put rage on, basic attack, basic attack etc. Rangers also don't really have any interesting unique things, being just a mix of Druid and Fighter really. So those two are ones I'd drop first. I'd drop Warlock too, but if that's confirmed, then probably Sorcerer. Not sure what the 4th one is, but probably Bard, Paladin or Monk.
Not sure if I'm that excited about it being Turn-based. Modern RPG design tends to include so much fights, turn-based can make the game really slow to play. So, hopefully they don't put too much fights in.
