to say they will come here or not next year is still a uncertainty because this particular round was to test Sepang and their management on having this race outside Japan...not because of lack reception from the locals here... at all.
It is their first time here so their are checking out the weather, places, broadcast packages and promotions that could be done FOR next year's race. No doubt that the Sepang track is in their list of challenging tracks for Formula Nippon so it'll be a waste not to continue the race here next year...
So keep your fringer's crossed yea but no worries... things are getting brighter with more of these japs INVADING our shore again hehe with loads of goodies and yummies :D
