IAHgames took their time getting a fresh announcement out today, saying that teleconferences ran overtime, but it's just come through in the last few minutes. The word is no character wipe for Hellgate: London in the Asia-Pacific region. The engineers at Flagship Studios have apparently found a way to migrate from the pre-production (beta) character system to the production (patch0 and later) character system without wiping everything clean.
The problem is pinned on the Asia-Pacific region going live 'simultaneously' with the USA servers. Actually, because they're on the Western side of the dateline, they went live the day before the USA, essentially running beta software.
