If we don't consider that magazine scan (which had mistakes), then the pokemons which are confirmed for the battle between Ash and Kotetsu are,

Ash - Pikachu, Pignite, Boldore
Kotetsu - Samurott, Swanna, Hydreigon

Also from all the previews and the short-manga scans so far, the following battles are confirmed (right),

Pikachu vs. Swanna (Winner - Pikachu)
Pikachu vs. Samurott (Winner - Pikachu)
Pignite vs. Samurott
Pignite vs. Hydreigon
Boldore vs. Hydreigon

Did i miss anything else.
You forgot Pikachu vs Lucario (I'm assuming Riolu evolves during it's battle with Pikachu).
