This may not be news to everyone here, but Adobe has released a
downloadable statementon its support policies for Intel-based Macs.
To summarize, it appears that Universal Binary versions of Creative Suite and other applications will appear only with the next versions, on Adobe's usual timeline of 18-24 months between major upgrades (not surprising); that CS2 has not been extensively tested running on Intel Macs via Rosetta, nor will this operating mode be supported by Adobe; and that performance degradations under Rosetta will occur.
As I said, not news, but there it is for those who are wondering about the upcoming transition to Intel Macs. I'm gonna be in that pack, as my 3 yr old PowerMac dual G4 is creaking under the strain of 1+GB TIFF's.
