For me I'm not looking to install as many vm's as i can possibly do. I'm looking to allocate more ram and processing power per VM to improve performance of older apps. Microsoft penalise users in this scenario which means i have less budget to licence development servers ect. I have 2 new dual 12 core servers so 48 cores. I have 8 VM's total and unlikely to need more. However I'm forced to licence 48 cores which is not cheap. Microsoft is assuming users are going to install as many VM's as possible which is not the case.....
