Actually, that's not what he's saying.

"A very basic theory on the two different structures could be lobbied at a large, established world versus a new world that hopes to entice players. Warhammer, if you weren't aware, is timeless to fans and the MMO from Mythic Entertainment is an extension of that established universe. Aion is a brand new experience from NCsoft that hopes to draw players in with beautiful visuals and rewarding tasks (ie. the ability to fly without use of a mount)."

I think his views on what both are trying to accomplish (conflict vs discovery) are possibly spot-on though, apparently they convey their message well from the start which is promising (though it'll probably not be so dry cut after sinking some time in either).
