Some say they will be new forms, some say they will be new Pokemon and some even say they'll be Reshiram/Zekrom's replacement. Does anyone know the truth? Or has it not been revealed yet?
When you catch Zekrom/Reshiram you will then be able to catch Kyurem, both will be at level 70. When Kyurem is caught it will leave behind an item called DNA Splicers.
Then to get White or Black Kyurem you have to fuse the two dragons - but they can be separated at any time.
It hasn't been revealed yet. But there certainly is a good chance of that happening. EDIT: It doesn't. You capture Zekrom/Reshiram ingame and fuse with Kyurem.
Actually it is true that zekrom and reshiram will be in a new form, zekrom combined with kyurem and reshiram combined kyurem, that's the whole point of the game. I know this because my cuz works at the Pokemon company
No, they won't replace reshiram or zekrom. Somewhere in the game you can catch reshiram/zekrom in the game. They will be found at the dragon spiral tower. You need them to make black or white kyurem
