I presume your car has manual transmission.
When you hit on the gas after fully releasing the clutch and your car revs up with very little or no power as if the clutch is still half released, it probably means your clutch has worn out and needs tightening or changing.
I do not know how much mileage that this will happen, I guess it depends very much on your driving habbits and how much abuse your clutch has gone through in the past. And if there isn't any of the above or other symtoms going on, then I personally don't think you need to change it at all!
This has been my personal experience a couple months back, and costed me some $3000HK, haha...
Hope it helps.
