So with the new DLC "Dawnguard" coming soon, I've heard that Vampires and even Werewolf damage will be buffed. I'm wondering if they are going to make mage spells scale now for Ps3 and 360 users?

Currently unknown.

Conventional wisdom is that some future DLC will buff mages...we just don't know which DLC.

We PC Users are still stuck using the same Magic system too, unless we add mods.

Hopefully they make the destruction perks that make certain elemental spells stronger affect ALL the spells. The Augmented Flames or whatever its called doesnt even make Wall of Flames or Flame Cloak stronger.

In all honesty, destruction is the only school of magic that needs re-balancing. However, all schools could use more spells to work with, not just more variations of the same spells we already have.
