Microsoft states in a blog on Technet.com that System Center 2012 SP1 will be released in early 2013. SP1 will bring a lot of new features but most important it will bring support for Windows Server 2012 Hyper-V.
The current release of System Center Virtual Machine Manager 2012 does not support Windows Server 2012 Hyper-V or Hyper-V Server 2012. It will not connect to a server running those versions. Also DPM 2012 does not support the new CSV 2.0.
Another new feature in SP1 will probably be support of VMware vSphere 5.0 in SCVMM 2012.
Currently SC2012 SP1 Beta is publicly available. Support is limited to TAP-customers. SP1 Beta is not supported and the EULA does not allow to run it in a production environment.
I blogged about the gap between releasing Hyper-V and SC2012 SP1 here in a posting titlted VMware will beat Microsoft on releasing a new version of virtualization platform?
