Context: Blizzard claimed for years there was no need for old school (original) World of Warcraft servers as the real demand wasn't anywhere near as big as the noise made for it, turned out after they finally gave in that they weren't just wrong they were astoundingly wrong as it more than doubled their expectations for demand (necessitating the amount of servers being doubled) and eclipsed the popularity of their last expansion lol.
