It seems Strider was quite right, and that Mexico wasn't really a goer finanically:
Teixeira: “The fact is that Mexico is a great fan base for us but, as a race, at the moment it costs us money. So Britain is the ideal place to finish off a season which has seen great racing but, frankly, was a bit disappointing."

Good to see Teixeira being honest about the fact that is has been a disappointing season, but bizarre decision making to re-schedule Mexico so late in the day in the middle of the economic pessimism. Instead of postponed because of the concert it should have just been cancelled there and then.
