So... if I may take the tongue out of cheek for a moment. I'm pretty sure they had said casters will you wands, staffs, and canes among a couple of other things I can't remember right now.
I may or may not have read this in leaked info. But lets be honest here, I can't even tell whats leaked and whats an "allowed leak" anymore. So I'm not trying to sort it, or anything. I can honestly say I don't go out of my way to try to look for unofficial info, so whatever I stumble across, I'm pretty sure that it's been discussed a million times already.
Let's say that...hypothetically
...there were people participating in the alpha who were doing a certain amount of dat mining (which could obviously not be the case because nobody would EVER dat mine a game in alpha, much less post the results). And let's say...hypothetically
that they found no explicit weapon type associated with any of the caster classes (hypothetically
announced or otherwise), then it might...possibly...suggest that the weapons used by casters may share certain physical characteristics but would, in fact, fall under different weapon categories. Hypothetically.
