dangerous, but is "worldcup " trademarked in OZ? i thnk it would be hard to trademark such a generic term, i'm sure rugby league would not let soccor do it etc etc , if not just because i associate it with soccor doesn't mean its not brandable for someone else, eg netball, table tennis, chess etc
think outside the square.
hold onto it and see what happens, maybe the worldcup of snooker or poker comes to australia then that is a valid reason to do another joint venture.
i can see it now on foxtel, bla bla poker every night 7pm from august 2nd, go to the website www.worldcup.com.au
