I still think that UFC.com should be the reference point for what is the official name of the events. A poster is simply a poster. There can be several different posters for the same event. Each poster can have different names for the event, depending on what market it is targeted to (e.g. for China, it's more important to mention that there are Chinese fighters in the card competing to be the first Ultimate Fighter; foi the rest of the countries, it's a fight night card which happens to have bouts with Chinese fighters). In the end of the day, UFC.com is surest reference for event names.
