I had read that about the coming memory improvements and it sounds great. When I got to %dayjob% the existing VMs had vast memory overcommitment issues (32 bit Std. servers with 8GB RAM allocated, etc.) I tweaked all of that and currently none of the hosts have more memory allocated to VMs than actually exists in the host. It's nice to know you can do it, however, if a genuine need arises.
