New EOS photo stuff from Canon

Canon has just announced new products, including a new digital EOS SLR, the 400D (in USA, the Digital Rebel XTi) and two new EF lenses, EF 50mm f/1.2L USM and EF 70-200mm f/4L IS USM.

Now, I'm not interested in the Rebels as I have 5D, but it's new sensor cleaning mechanism sounds nice. Of course, it must work, too. But to me, the new 50mm lens sounds very nice. I bet it costs more than a grand.
