Using a script Shay Levy wrote HERE, I have the following list of cmdlet changes that have occurred between Microsoft System Center Virtual Machine Manager 2008 R2 and the very recently released 2012 Beta 1 (see HERE).
  So below is a listing of the parameter changes to each of the cmdlets.  There are several changes in the new Beta...  There are a few cmdlets that have parameters that have changed, but along with the new features announced in 2012 Beta 1, there’s a load of new cmdlets covering the features planned for VMM 2012 (due apparently by the end of the 2011 calendar year).
  Cmdlets with an “!” have changed, and have a “+” or “-“, depending on whether the parameter was added or removed.  For the new cmdlets, they are just have a “+” and their parameters aren’t listed, while cmdlets removed have a “-“.
  The list does have a small surprise: the SCVMM team has renamed some of their cmdlets to have “SC” in the noun.  So, you’ll see “Add-SCVMHost” being added, and “Add-VMHost” being removed, if you look closely.
