It's a old chinese proverb. A man who chases two rabbits lets them both get away, and like everything it doesn't apply to all aspects of life.

Really the people in the middleground are the people in the right, because the new servers could still be in Japan and would still experience less lag. They were connected to Japan at gamescone with no visible lag on commands or anything showing that the game is much more responsive than it currently is (Probably due to letting more stuff be checked client side).

But the people for the data centers either don't think it will be enough or are just ignorant to the fact the servers were the issue and not the latency.
