[G4] G5 and photoshop

[Mel]

Kunga,
As a project manager for software development, I must disagree with 
your characterization of migrating applications from 32 to 64 bits. I'm 
afraid that is nothing like trivial, and for many applications would 
not even be useful. As you pointed out, the higher bus speed and the 
greater memory throughput will generate breathtaking improvements that 
have been long overdue. The OS will take its time migrating from 32 to 
64 bits, just as it took its time migrating from 680x0 to PPC native. 
Applications will do the same. The OS doesn't need to be fully 64 bit 
to take advantage of some of the features of the chip right away.
It would be great if Photoshop would be 64 bits by the time the G5s 
delivered, but the OS won't even be fully 64 bit. The most immediate 
need is to make memory addressing see more RAM, and as I understand 
10.2.7, which will be the OS on the new G5s, has implemented that 
feature.
Just my two cents,
Mel
