We have reported in these columns that the new Circuit of the Americas coming up at Austin, Texas has signed a ten year deal with MotoGP promoters Dorna for holding the Moto GP races starting from the year 2013.  Apparently this move has started causing some anxiety to the other two promoters of MotoGP races in America, Laguna Seca and Indianapolis.  Laguna Seca holds only the Motogp race and not the Moto2 and 125cc (to be Moto3 with 250cc four stroke engines) from next year on, the Indianapolis Speedway hosts all three categories.  Austin has signed to host all three categories as well and this is causing concern especially at Indianapolis whose contract to host MotoGP races expires at the end of this year.  Laguna Seca came into prominence due to the efforts of racing legend Wayne Rainey and perhaps it is the least threatened of the two existing circuits.  It is also possible that there will be three races in the USA.  Already Spain has four races.  If new circuits in other parts of the world have to host MotoGP races, some of these existing ones may have to be dropped.
