Whoops, I meant to post this a while back. I also contacted them after noticing the Ingenuiteas I ordered this year were different from previous orders.
As other posters mentioned, they no longer come with the coaster. This isn't really a great loss to me since they drip so little I never bothered to use it (same with the Clever Coffee Dripper which comes with an identical coaster). The biggest difference is probably that the moving part in the base is now a darker plastic which I assume is meant to hide long-term staining from tea. I didn't really like the way it looked at first, but I don't notice anymore. They describe this as their "new model for 2011".
