It's looking increasingly likely there will be no race in Japan this year, I'd imagine they are waiting until the olympics finish until they make a decision. Joe Saward reported some rumours of them planning 2 races in Texas and 2 in Mexico over the space of 5 weeks to fill the slot left by Japan and Singapore. I fully expect at least one more round at Bahrain where Australia was and the inevitable cancellation of the race in Brazil. It's bizarre to think that there is only one race on the calendar for November and we are still going until mid December.
