If this is true why didn't they actually at least talk about it on WWDC?! It would have made it interesting at least!
Ahh, but now maybe this was one of the "super secret features" of Leopard. No need to announce Xcode for Windows until Leopard actually ships, now do we?.
Prior to the switch to Intel, Apple kept saying: move to Xcode, move to Xcode, move to Xcode. Those that did were ahead of the game when Apple switched to Intel. Those that didn't had to play catch-up. I think there might be more to Steve's touting CoreAnimation, CoreAudio, CoreThis, and CoreThat, than just a simple surface level "Don't we have an awesome OS." I sense some ominous foreshadowing in the works.
If the developer tools are good enough, and the user experience excellent enough, then the underling OS might actually become largely irrelevant--much as it is with the Internet.
I remember seeing one of the first NeXT computers demonstrated. It made Apple, Microsoft, and IBM look like they had been asleep for twenty years--and this was only 5 to 7 years (1989-1991) after the Mac was introduced (1984). Apple and IBM panicked and tried to create
Taligent as a response, and Microsoft started spreading FUD and blathering on about
Cairo which sort of became Windows 95, Windows NT, and some of it (WinFS) is still under development 16 years later.
Apple now seems poised to pull a "NeXTSTEP" in the cell phone market with the iPhone.
Might they also have their sights set on other targets. I'd be awfully anxious about Apple if I were Google or Microsoft.
