As I've stated before, we've had two continents and a revamped Eastern Kingdoms/Kailmdor. Plus Blizzard stating that naga as a race would look weird as they have no legs. Take into account also what Apathy said and all signs point to a long and overdue Burning Legion. Of course it's merely speculation, but compare what I've (and others) said to what you believe will be naga and it's clear it's not them. There is no signs whatsoever of it being naga. It's just your opinion with nothing to back it up. Just that you feel it should be them and that Blizzard is "lazy". lol.
