I don't know if this adds anything concrete but I just attended an Apple, Adobe and others event. The guy from Apple alluded to Leopard coming out in a few weeks. He didn't actually say it but 1) he said that Apple tends to underpromise and overdeliver on timelines and 2) he made a slip (intentionally?) when he said "when Leopard comes out in a few weeks, um, I mean, a few months" with a big grin. So, I still have hope for a release earlier than June. The money is burning a hole in my pocket for a new MacPro, MacBook Pro and CS3! Broke city here I come...
P.S. At this event, I also got a free copy of a piece of software called Crossover from a company called CodeWeavers. It allows an Intel mac user to use a large variety of Windows-based apps, including Office, Outlook and some games, without having Windows installed whatsoever. The company is a major member of an open source project called Wine that has been making pc programs available to Linux machines and now that Macs are Intel-based they have brought this capability to the mac. Doesn't work for every single Windows app yet but an impressive number of major ones and it isn't emulation, you use the mac finder as usual, no switching back and forth, etc. Can't wait to get an Intel mac and try it out!
