I'd guess iLife '10.
They are not system apps.
Do you think that the consumer apps will require a paid update to go Cocoa/64-bit?
I only ask because Apple just released FCS3 and LS2 before Snow Leopard. That doesn't make any sense to meunless they're planning on a point release for each of the apps in the suites, giving them GCT goodnessbecause updates only happen once every two years or so.
Do you think that Apple would allow their professional apps to sit with two-year-old technology, having been released JUST prior to their multithreading tech?
I just don't see Apple making professionals pay for Snow Leopard enhancements to FCS2 and LS2 (and Aperture 3, yet to be released), but I do see iWork '10 and iLife '10 being the first we see such things on the consumer front.
