Dragon Ball Z: Ultimate Tenkaichi is set to launch in October on the PS3 and Xbox 360, but those who pre-order the game in Japan are set to receive a very special gift upon doing so. According to Silconera, a retail leak has shown that an actual four-starred Dragon Ball will be given to anyone who puts a payment down on the game early. As of now, no retailers have announced a pre-order incentive for Ultimate Tenkaichi in Europe or North America, so just maybe Namco Bandai will pull this gem (or ball for that matter) out of their sleeve for some extra hype down the road.
When it comes to any Dragon Ball game though, the Tenkaichi titles are in my opinion the definitive out of what we have seen released, so this upcoming successor should sell well on name alone. I will say however if one of you happen to import the Japanese version from Japan, you can use your Dragon Ball to wish for the same treatment to happen in the west.
