Tough times ahead for F1?

Times are really hard. The F1 scene has seen some casualties of which the Honda team is now up for sale as they have decided to pull out for good. Then there is the 1 engine supplier which has seen top teams threatening to pull out altogether. Some race circuits are not having it good as they still owe money to the FIA which puts them at risk of not being able to host the next round of F1 when the 2009 season starts. Seems that F1 is riding to the sunset?
