I don't know where the future lies for Rossi. Honda will not take him back, there was bad blood there apparently, nor Yamaha. This was always the fear if this latest Ducati didnt work, that it could be the end. Rossi is too big to hang around in lower teams like a lot of riders do.
Unless however, he wants to go to WSBK, which I reckon would be the most likely if he wants to stay on bikes, and would be a hoot for WSBK and Rossi.
Rossi likes and needs fun, look at his personality for goodness sake - which is the best sporting personality Ive ever seen in any sport bar none, West Indian cricketers from the 80's are second and the only thing that comes close - it needs fun to function.
This to me explains his outburst; he aint having fun at the moment, he needs fun, and its a big big problem for him that he isn't. Go to WSBK Rossi and liven it up for us, for me WSBK is a bit of a yawn-athon at the moment.
But this also leads me to believe he'll head to rally cars for pusuit of fun and where he knows he's damn good too.
