Is OS X 10.2 going to be 64-bit?

Is OS X 10.2 going to be 64-bit? I was thinking that if it is not 64-bit, then the G5 will not come out in MWNY. What do you guys think?

Maybe X is already 64 bit

And that's why it's's running "choked down". This would mean MWNY will leave us drooling.

All up in your bidness
I was under the impression that there would be both 32 and 64-bit versions of the G5 available. A 64-bit G5 would not necessarily be any faster than a 32-bit G5. (In fact it would probably be slightly slower.) Making an entire OS 64-bit clean is a big job if OS X isn't already, and I would think it would be very unlikely for Apple to support this any earlier than OS 11.

The MIPS R4k series of CPUs shipped in SGI workstations from 1991-1996, but they only ran a 32-bit OS and 32-bit software. It wasn't until 1996 and the R8000/R10000 that SGI supported a true 64-bit OS in IRIX 6.0-6.1 and >6.4 (I think). I realize MIPS and SGI have nothing to do with Apple, but just to give a bit of perspective.

Nothing is impossible.

good theory...but impossible. Programs are not backwards compatable.

Only ever highly improbable.It is very unlikely but it certainly would explain OS X's excentricities.

suuuure... a brand new chip (remember the G4's yield problems?), at a much higher clock speed than anything else they've released (more yield problems), being used in a dual processor machine? I think not. I could be wrong (I hope I'm wrong), but it doesn't seem real likely. My current guess (assuming the rumors about a 500MHz RapidIO bus are correct) is 1.25, 1.5, 1.75GHz, or 1.5, 1.75, 2Ghz , being released at MWSF 2003. I would expect (again assuming the rumors are semi correct), a higher clockspeed G4 (somewhere between 1.06 and 1.33GHz [4, 4.5, and 5 bus multipliers]) with DDR ram in the summer. the 7455 name in the current G4's chip says to me that it was a very small chip upgrade indeed (I think the only tweaks were DDR cache, and a new manufacturing process. Other than the cache, the design appears to be the same). The first G4 was the 7400, then it jumped 50 to 7450. This one only jumped 5.

Well, it's about as possible as 2 + 2 equaling 5. :)
ok, then, you newbies to the techie field, here is your chance to make your "mark" on the IT field

i made my mark by being among the first to actually use a personal computer when i was in school...and that was considered amazing in itself...there was this incredible mystique about being able to use a machine as if you had to be a nerd, be smart, and be terribly bad with the opposite sex

that stereotype is where bill gates came in and initially became a hero to us nerds/geeks until we later saw what he really was
