Will Guild Wars 2 have a 4th expansion?

I'm curious, will Guild Wars 2 be getting a fourth expansion in the NEAR future? Fans of the game have been eagerly anticipating news about any potential new content, and with the previous expansions being so well-received, it seems like a natural progression for the franchise. Do you have any insight into whether or not we can expect a new expansion, and if so, what might be in store for players?
