do you have pointers to the efficency claims for capacity/power savings growing that significantly?
the other issue is that electricity is pretty cheap, so it takes a LOT of power savings to equal the cost of a new server.
The case for the /usr merge

also, this sort of savings from virtualization assumes that you are running your prior servers lightly loaded. If you have an application that is large enough that you need to run it on multiple machines to start with, virtualization is a net loss (although this net loss is frequently covered by by doing the consolidation at the same time as a server upgrade)
I don't know about your servers, but on the ones I am seeing 8-12 cores with 64-128G of ram takes significantly more power than the 2-core servers with 4-8G of ram that I still have in production. measurements show somewhere between 2x and 3x
