Exchange 2007 SP1 will be released in the second half of this year. A partial list of what you'll find included in this SP is:
Standby Continuous Replication (SCR)
With Exchange 2007, we introduced Cluster Continuous Replication (CCR) for replication of data between 2 servers within a cluster. With SCR, data can be replicated on a per-storage group basis to standby servers or clusters. The SCR target, whether a single mailbox server or a cluster, can be placed inside the primary datacenter or in a remote location, ready to be manually activated if the primary server or datacenter fails.

I am awaiting the release of SP1 before I implement Exchange 2007 period. After testing it for several months I believe it is seriously more trouble than it's worth. The OWA looks great but come on people...let's see how complicated we can really make life.
