The Time Jumps...

So I have to wonder are the time jumps over?....The last we see there is Kate, Hurley and Jack in the lagoon and Jin there to see them. But are we to think that the others on the plane landed in a different time?? Only time will tell!! I am also thinking Hurley has his guitar for Charlie reasons...I think Charlie is possibly the one that told him about the flight and how he needed to be on it. All the time jumps makes my head hurt lately!! More to come later....
