Photoshop CS3 won't be 64-bit
Adobe will be releasing a 64-bit version of Photoshop, at some point. Photoshop CS3 is not going to be 64-bit despite some demand for it (64-bit apps can access more physical memory, amongst other things). Why? Adobe points to the lack of adoption of 64-bit technology by consumers. Tiger has limited support for 64-bit applications, but it isn't complete (Leopard promises more in this area) while 64-bit versions of Windows are available most people don't know about them and wouldn't care if they did.
Patience, Photoshop jockeys, your 64-bit version of PS will come sooner or later.
