Monster materials don't confirm a monster though. I can trade G.Jaggi parts for Arzuros parts, Kechawacha parts for Qurupeco parts etc. I doubt that the trading system will have materials from monsters as high-level as Stygian Zin though, but I'd personally wait until we have more solid confirmation (i.e. image, video etc.).
