From http://www.pitpass.com/fes_php/pitpass_news_item.php?fes_art_id=33877 Are you an F1 fan or a GP1 fan?
Probably a slip. They were talking about merging football clubs with racing a few years ago, I seem to recall. I don't really see much room between F1 and GP2 unless F1 completely implodes at some point. I think BernieCo merely reserves GP1 as an out in case there ever comes a time when the racing world falls apart. They can use it as a title to avoid any legal issues.
