Not for OS X.

It does include a discussion of the 64 bit advantage, what Adobe considers to be recommended amounts of RAM and it mentions a couple of things on the roadmap so I thought given some of the discussions, it might be interesting when thinking of new Macs.

CS5 will be written as 64-bit, and not only that, but written FOR Snow Leopard.

We'll see some very interesting things with CS5, I believe.

Only Photoshop. According to the white paper Lightroom (of which I make substantial use), After Effects and the remaining CS4 apps are 64 bit. My guess would be that Adobe has a crapload of legacy code in PS that they're trying to rewrite.
 
From a quick reading of the document observing it's focus on video work flows, it doesn't appear that 64-bit will be of much use to print designers. I had always assumed a 64-bit OS and compatible software would by definition be much faster, but perhaps that's just a stupid artist thing to think.
