Oh- I see the review just came oout, and they've been working on it for 8 months and the camera was announced in 8/2007, so the 50D will be announced a year later, but probably not available until February? maybe for Xmas?

Full frame it is, but laking if the 50D comes out as such...
Hope to figure out a way I can upgrade, but my 30D won't be worth much.
