Formula One to lose Ferrari?

Not yet at any rate. News is just in that Ferrari have signed up for next season albeit with conditions. But, it looks like the argument over budget capping is going to rumble on for a while yet. Anyway, whatever budget cap is imposed I can't see how it can be very effectively policed. It will always be possible to hide the financing of development somewhere. Perhaps the best we can all hope for is that the big teams agree to help the introduction of new blood. After all the more teams they beat the better they look! Or is that why they're worried?
