Along with the G12, Canon's SX30 IS camera has a couple of updates that SX20 owners will frown at—but on the whole, it's really just the super telephoto lens which will bring out the green facial hues.
Canon's G12 is a lot like the fantastic G11 pro point-and-shoot. Same sensor, practically same body, but now with 720p HD video and a "high sensitivity" mode. No fantastical advances—on the upside, G11 owners, don't you feel better?
If you thought that Voltron or Power Rangers was entertaining, wait until you see Engine Oh G12. Its robot is assembled from twelve different vehicles, including a shark car.
