An Adobe blog by John Nack addresses some recent concerns due to a recent release of the beta of their new SoundBooth application which is available for Intel Macs only.
Nack reassures customers that Adobe's existing applications will be released as Universal (both Intel and PowerPC) for now:
As regards Photoshop, Flash, Dreamweaver, Illustrator, etc., these apps have been tuned for PowerPC for many versions, and therefore continuing that support is a very different matter than creating support from scratch. To put the freaking out to rest: the next versions of the CS and Studio apps are being built as Universal apps, and they'll run great on PPC. Someday Apple, Adobe, and everyone else will stop supporting PPC, as they did with 68k chips, OS 9, etc.--but not anytime soon.
According to Nack, focusing on Intel-only for SoundBooth allowed Adobe to bring the application to market faster and with a richer feature set. That being said, it appears clear that there are no plans for providing PowerPC support in new applications such as Soundbooth:
And again, in order to migrate, you have to start somewhere (namely, on the PPC). Soundbooth is a fresh start, not a migration.
