Cassini in 2013 and beyond

We'll begin working on making Cassini the default search engine in other major markets later in the year. We're beginning to test it in the UK, and we'll work on Germany soon too. There's also a ton of logistics to cover in launching the engine: cassini requires thousands of computers in several data centers.

We'll also begin to innovate even faster in making search better. Now that we've got our new platform, our search science team can begin trying new features and work even faster to deliver better results for our customers. As a team, we'll blog more about those changes.

We have much more work to do in replacing Voyager.

There's much more there, ^ mostly rumination/repetition and buzzphrases. Indicated also, we can all, worldwide expect more 'tweaking' (by any name)

Sellers can expect to see traffic patterns such as this. (or worse)

There are a good many discussions regarding the issues worldwide on English language sites already such as in the USA, the UK and Australia.

Be prepared though, as ebaY speaks only Bahnhof. ;p
