I don't know if you heard this on the AO broadcast, but according to Darren Cahill, Ljubicic screwed himself by switching racquets (from Babolat Pure Drive to Head Extreme) after his most successful year. Supposedly, Ljubicic switched in exchange for a boatload of cash and a promise of a position after tennis, and his game has really suffered since the switch.
According to Cahill, no one in the top ten has switched in the last 3 years or more because you would never change given success.
