The really relevant bit was the Lola/Toyota/Lotus/whatever else car thar broke the perfect Audi result, but then again "relevant" is also relative here.
Le Mans really needs competition, but even if automakers are willing to dump enough money on an effort, they are 11 years behind Audi in terms of reliability and expertisse and know-how, and when they cannot take them down most of the times they simply drop the program (add to that that economics are crap right now).
As much as I hate Toyota, I hope they'll be back next year ad that Peugeot, as much as I hate them too, also get their program running again. Porsche returning to the top-tier class would for sure put some excitement in the race... heck, even if they just make the Audi team worry about having a rival car behind them for the entire race, it will be better than this.
