According to my monthly Omniture newsletter, Omniture will be releasing Version 2.2 of SearchCenter tomorrow. This is actually a fairly big release because they will now be supporting Microsoft adCenter. This brings their total to 7 engines and 40+ Websites.

"Version 2.2 includes a bi-directional synchronization with the search engines which allows for greater flexibility to manage keywords on either the SearchCenter interface or on the search engine interface."

The lack of speed for synchronization was something SearchCenter users were looking to see improvements on. In the current version synchronization is done daily.
