Actually, I'm not sure if we should keep this method. There was a transition time period when only English hubs where switched to WikiaHubsV2 but now all WikiaHubs are replaced by WikiaHubsV2. Therefore, I think we could come with foundation that all corporate pages use WikiaHubsV2 extension. And then we'll probably have to extract CityVisualization::getCorporateSitesList() and make it public. What do you think about this approach?
