Best way to protect physical Windows clusters at secondary DR site?

We have numerous Windows 2008 R2 server clusters in a central data center and are looking to provide secondary site fail-over.  I have been looking at Windows 2012 R2 features coming later in the year and also third party solutions such as Double Take Availability.

I am hoping to get a 1 redundant GBps VPN site to site connection between the two sites.  We have NetApp SANs and SnapMirror licensing and use iSCSI LUNs.

I know the future is virtualization and cloud, but we have significant new hardware waiting to be used.  I have been thinking to have the secondary site to be perhaps a Hyper-V 2012 private cloud.

Thanks so much!
