On the one hand we hear that there are race promoters queuing around the block begging to be allowed new rounds of the FIA Formula 1 world championship.

Yet in the wake of Bahrain’s almost inevitable decision to shelve its Grand Prix for the time being, cautionary noises could be discerned from elsewhere on the international calendar.

There are more voices from within Australia suggesting that Melbourne should fight shy of renewing what some feel is a prohibitively costly Grand Prix when the current contract comes up for renewal in 2015.

At the same time Artur Mas, the president of Spain’s Catalunya region, has gently warned that Barcelona’s continuation as host to the Spanish GP depends on how the commercial bottom line unfolds over the next couple of years.

“The continuation of the F1 race is guaranteed for this year and probably next year too,” said Mas on a visit to the Circuit de Catalunya pit lane during this week’s F1 test at the Spanish track. “And I trust it will continue here in the future. But that will depend on how the economic situation develops and the results we have over those two years.”
