Several questions remain unanswered at this point, including what name the new series will take and what types of cars it will run. Both will surely include GT racers like the new NSX, Porsche
911 and Ferrari
458, but each of the series has its own types of top-tier racers. Grand-Am runs Daytona Prototypes while ALMS uses Le Mans Prototypes (in the LMP1 and LMP2 classes). Just which makes the cut-off in the merger remains to be seen. Of course the NSX isn't likely to be confined to American GT racing, so look for it to compete in series like Super GT, the FIA GT1 World Championship and the Blancpain Endurance Series as well.
