The Ferrari veto is pretty much in place. All the French court said was that, it, the veto had not been used at the right time, i.e. Ferrari should have used their veto when the budget cap etc was being talked about. It has not affected their right to veto anything that comes up in future.
The manufacturers, if they decide to go for a break away, which as you rightly said is highly unlikely, will not care much. They are not in F1 to make money as such. They are in F1 for success which translates into sales from their production cars and that's where their money comes from. So, in the unlikely scenario of a break away they will continue to have the support of the majority and emerging markets will want the break away series to have races in their countries so in my opinion they stand to gain from it. By staying in F1 and going along with FIA they will lose in the long run anyway. The budget cap and all the other regulations will make the field very tight and increase the likelihood of another Brawn emerging every few years. Looking at things right now, Mercedes and Renault can't be happy at the way things are. Their customer teams one and two in the constructors race and the drivers occupy first to fourth places.
I think that is another rumour. FOTA might not need most if any of those tracks. Brands Hatch, i don't feel is upto F1 standards. FOTA don't need to worry about tracks. Montreal is available, so is Indy. Those are two tracks that will look after a huge market in North America and one would need to think if the USF1 GP makes it into F1 whether they would want to be part of FIA or the break away series.
Silverstone has no contract after this year with FIA, Imola has been sidelined, A1 ring, the new track in Portugal. South Africa has been quite keen to hold a GP again and have everything in place. China, was said not to be too keen on carrying on given the money they pay to Bernie, they will be happy to go with FOTA, Fuji in Japan is another track which will be available and in Japan they have probably 5-6 tracks worthy of holding an F1 race. Not saying they will all hold grand prix, but in the past we have had Japan hold two races, the Japanese GP and the Pacific GP. There will be so many other who will pop up. Tracks are not owned by FIA, they will not be a problem.
Interesting case will be of the major television companies. The Italians are rumoured to have an understanding with FIA, that the series they show must have Ferrari. BBC, who paid big bucks last year to buy F1 rights, do they want to show a series where Button or Hamilton is winning or one, where Adrian Sutil is leading? Same goes for Spain, Brazil etc.
Max is fighting a losing battle, the sport right now cannot survive without people like Alonso, Raikkonen, Hamilton, Kubica, Massa, Button, Vettel, Webber and the big teams.
