Since a few legits have jumped in here (and I'll understand if this hits an NDA and you can't say), I'll ask a question that will hopefully be put in a way you can answer.
I have a concern about whether existing software will run in the new 10.6.
I base this on experience from the transition to OS X from OS 9. And, on the experience of the transition from PowerPC to Intel.
I have entertained the thought, that if Apple really is reworking all the frameworks and underlying technologies, that essentially we could end up with 10.5 "appearance" and functionality implemented with new supporting code and essentially a new means of getting something that looks the same.
My thoughts, are that perhaps we will have something that on the surface is functionally similar. But, not implemented the same way. And, my concerns are that existing software may cease to work because of this.
I wonder how many of the new "Universal" apps will work unmodified. And, I wonder specifically about programs like iMovie 6.
I know from experience that many programs have required minor point revisions to get them to run properly in the new versions of OS X. And, those versions of OS X didn't really change the underlying technology as significantly as Apple claims this new release will.
So, I am left wondering if we're going to have a jump as significant as the jump from OS 9 to OS X. Or, if this jump is going to be relatively unnoticeable.
Unless Apple brings the old iMovie 6 back to life in a reincarnation of sorts, I may have to stay with Leopard 10.5 just to know that I can continue using iMovie in a useful form (useful to me).
If PowerPC is truly phased out, then I would naturally assume that's the end for 100% PowerPC programs. But, what about those that were updated to "Universal" status?
And, I would expect that this likely is the end for Rosetta (PowerPC emulation / translation). But, I know you probably cannot say.
I would appreciate any comments you can offer in regards to my above concerns. If it hits NDA, then I understand. But, if you can say, then I'd appreciate your observations.
