System Center Operations Manager will have proper SP2010 support. Just announced at the Microsoft SharePoint Team Blog:
Management Packs allow users to monitor SharePoint 2010 with System Center Operations Manager. SharePoint Foundation Management Pack and SharePoint Server 2010 Management Pack enables monitoring of SharePoint Foundation 2010, SharePoint Server 2010, Search Server 2010 (These is separate management pack for FAST search), Project Server 2010 and Office Web Apps. Once management pack is imported to System Center console, based on console configuration it automatically discovers what SharePoint bits or servers are installed in the environment that is being monitored and start monitoring those components.
These 2010 management packs will be released to System Center Operations manager catalog and will also be released to web along with SharePoint 2010 RTM.
