For the twitter users amoung us, you should definitely add Katsuhiro Harada to your following list. This man basically IS Tekken, as you can see from his profile he is the Game Director/Chief Producer of Fighting Games for Namco, leading the Tekken Project.
I (Mike) decided to ask him a question in regards to whether or not the proposed Bana-Pass will work outside Korean and Japan, as there is much speculation that it won’t.
While this is far from a confirmation, I believe it at least shows that TEKKEN-NET in Australia is being strongly considered, so there is definitely a chance we will see it come TTT2. For now we can keep hoping though, note his careful use of “probably”!
