Plowman: I'm not sure whether or not we'll see a big price drop. Most likely the quads will go down, because they're *very* expensive. But historically, Macs haven't really dropped all that much when new models came out.
dpcon the outrageous: I don't yet know how much RAM you can access with Vienna Instruments (because it might be using memory outside the host?) - I'm going to find out as soon as I put another hard drive in my machine - but remember, OS X uses as much RAM as you have available for caching. 5 or 6GB is definitely worth putting in for that reason; whether 8GB is past the point of dimishing returns I don't know.
OS X can use 4GB for each program minus a little less than 1GB for frameworks and system libraries (shared between all the progams); .5GB for the OS outside the progam; and some RAM for caching. So if you have 4-1/2GB, you have nothing left for caching when your DAW is maxed out.
