No way. Adding content on this kind of scale (50% increase to the map?) will result in so many bugs... still, I am kind of looking forward to seeing it.
Waste of time imo. That time could've been put in to buffing dead content and finishing the rest of Gielenor. Now we'll get a buggy continent that half works and won't even be released till 2018. Which honestly I don't think people will still be playing in 2018.
