This is a question for fun, just to see how old y'all are! I asked a group of photographers and nobody came back to me with an answer. Let's see how you do. The first one to answer both parts correctly and completely will be awarded with ten points.
Why do some 35 mm SLR's sync with the flash at 1/60 and others at 1/125?
Why do some larger format cameras sync at even higher speeds than the smaller SLR's?
Get busy. We'll see who is as old as me with this one... :-)

Obviously, the pros know the answer, so maybe we should disqualify you guys.

Well, y'all can answer anything you please, but I might not give the pros ten points. You are either older than I thought or steeped in history.
Maybe we can add a bonus round asking you to explain the difference in material choice that makes some focal plane shutters faster than others...
We're just having fun today - spending some of my Yahoo! points - so answer the long or short of it depending on your mood.

Teef - hint, hint - Your Fuji does not have a focal plane shutter.

I guess I can close this one out. Maybe I should not have said "disqualified" to the pros, as there would have been more interesting answers.
Horizontal travel focal plane shutters - generally made of rubberized or plain fabric with metal edges - take longer to fully open than vertical travel shutters - generally made of metal - which have a shorter distance to go. This is why horizontal FP shutters sync at 1/60 and vertical FP at 1/125.
What was the name for those vertical travel FP shutters? I remember that they had some sort of name that was used in the advertisements... I guess I can "ask" that here.
Leaf shutters pop open and then close without travelling across the film plane, so they sync when the shutter is wide open. This can be at pretty much any speed you choose, up to 1/500 in most cases. I remember Compur shutters, which seem to have been replaced as the indutry leader by Copal shutters.

I have a d80, and it has a setting that will allow you to use the sb600 sb800 or sb900 flashes as fast as the shutter allows. (even though the sync speed is only listed as what you say for the camera itself) Let me go home and look at what the setting is called and see if it is available on your models. If your cameras DO have this setting, all you have to do is turn it on to allow faster syncing !!!! If its NOT available, you should be finding that you can only set your shutter speed as high as the rated sync allows.....EG...with my d80 and just the popupflash...when i turn the flash on, the shutter will only turn to 1/200th. not sure WHY in the world nikon started lowering the rated sync speeds!!! Its a mystery. Hi Julie....just got home and looked at my d80....If you look in your custom settings menu...look for something called AUTO FP....on mine its number 25. From my understanding, if you turn the auto FP function ON, then when you use a dedicated flash like the sb600, sb800 or sb900, you have a flash sync speed as high as your shutter speed can go....it overrides the limitation of the camera's defined shutter sync speed. Once again, that's what my understanding is. Unfortunately, I don't have one of these three flashes yet, so I haven't been able to test it out. Once again, I'm not entirely sure if the d200 or d70 HAVE this Auto FP feature.

Ahh.. he is correct.
A focal plane shutter - a shutter speed must be long enough that first curtain reaches the end of its travel and then a brief instant passes before the second curtain begins its journey across the frame.
:-)
Addendum: My Nikon FM2's shutter is made out of titanium. I think it was a breakthrough at the time, thus, faster sync. I do love that camera.. but it's not cheap to use now..

Does it actually have anything to do with the difference between focal plane and leaf shutters? Because even though I can see how the old leaf shutter is so show, I really can't see how the focal plane would be any different. Has to move one way then back again. Actually, I don't even see how I can get 1/8000 sec from my camera but I do. This is driving me insane...

I agree with antoni as well. And since I couldn't just bust out with a clever answer, I'd like to add that an electronic shutter also yields a faster sync speed. Yes, electronic. That means every point and shoot digital camera has a shutter capable of speeds into the one thousanths of a second, if only they had a flash sync port which most don't. The nikon D70 with its electronic shutter can sync that fast, but is limited to 1/500th unless you trick it out with a non-TTL sync cord. That's an interesting bit of info I'd like to share as my contribution.

Sorry Sam, I know my old slr synced at 1/60th but I don't know why. I am interested to see the answer when it's posted...
guess that makes me a young un.

OK explain to me why my my Fuji S9500 P&S will flash sync up to 1/500?
