About the abilites.
It should be aparant to everyone that Gamefreak won't introduc a new ability in the middle of a geration. Have they done it before? No. I am getting exteremely pissed at anyone thinking a new ability will be introduced. The theorizing on these new Kyurem forms has gotten rediculous with no new information.
Glaciate will remove the charge turn of Freeze Shock/Ice Burn. You heard it here first.
I think the only move or ability to get a change will be Glaciate.
That unique effect number has to go to something
It was said that these kyurems change forms by emotions, into something called "overdrive". Overdrive sounds like your doing things faster than the standard, perhaps while in the separate overdrive forms your freezeburn/shock will not require a turn to charge. Which would be nifty if changes outside of battle, but if in battle it's kindve meh. Not gonna speculate on bst, but overdrive sounds so right for that.
Gamefreak has stated like 10 times in various interviews types and type charts aren't changing. Gen II only changed things because Psychic was super OP.
At least poison types in gen 1 were super effective against Bugs! Granted bugs were SE against poison but that's beside the pointOverdrive does sound like a new ability, perhaps Kyurem does receive it? Would sure make Freeze Shock and Ice Burn more viable. And Poison-types have been the worst attacking type in the game since Gen I IMO, although Steel is pretty bad as an attacking type as well. Defensively, they're pretty good though, so it isn't ALL bad for Poison types.

I would love to see poison become something more than it is now. The most logical thing in my opinion would be SE against bug-type (reference to insecticides, that sort of thing) and fighting-type (you can't fight well when you're badly poisoned, or can you?). But alas, I don't see this happening anytime soon.
Water type!
Be super effective against Water type!
