I have hope that with their backs against the wall that they will finally make the appropriate changes to the grass season in the next 5 years or so.
This is never going to happen. Everyone has complained about this at some point, over years and years, and it's never been changed. Wimbledon and the French already have their solid places in the calendar, particularly Wimbledon. The French would need to be moved forward but I still don't see that happening.
And where exactly are all these extra grass tournaments going to take place? Really the only places capable of maintaining top class grasscourts fit for a professional tennis event are already all in use.
Like Shvedbarilescu said, Wimbledon is bigger than the players. It makes the players, not the other way round.
The grasscourt season has been the same since Venus, Serena, Mauresmo, Davenport, Sharapova, Graf etc. etc. were playing. They likely didn't play their first matches on the surface until they started playing international tournaments, yet they were all obviously very comfortable on the surface.
The whole tour right now is less predictable and less dominated. This is true everywhere not just on grass. And I don't think Wimbledon was ever necessarily any more "exclusive" than the other slams, since they've all been equal and all had all of the best players. It's just we put Wimbledon champions on a higher pedastel, because it's Wimbledon.
