I fully expect multiple guilds to join too, but I don't think the WS will decide the conflict. After all, Laxus, Erza, Natsu, possibly Gray, Gildarts(if he returns), Mirajane, Makarov, Minerva, Kagura, Lyon, Sting/Rogue(as a combo) and Jura are all pretty much mid-to-low-tier Wizard Saint level fighters.
