Where is motorsport going - what will survive?

[Stella star]

Looking at the news recently we have teams pulling out of various forms of high-profile motorsport beacuse car manufacturers simply do not have the money to compete. It has also been said that they don't get enough out of the motorsport (presumably sales and brand prestige?) to make it worthwhile.

So where is that going to leave motorsport - will F1 continue - what'll happen to WRC if we say have 3 teams competeing ?

Maybe there'll be a big return to grass roots stuff and low level or more local motorsport?

Thoughts anyone?
