There is now a new model Weber Genesis, called "Genesis II", available in US and UK. See US Weber site:

None of the models have a sear burner anymore but have a + setting which may or may not give the same heat output. All models have different burner tubes with punched holes of graded sizes rather than slits that are meant to clog less and give more even heat and different flavorizer bars.
There is some debate on the overseas sites as to whether they are made as well or have had some costs cut. All the reviews I could find were just photos of shop demo models and there were no hands on cooking tests as yet.
Weber-Stephen Australia say that they are unlikely to have the new models before August at the earliest and are unsure what models will be imported or at what price.
