Is anyone else excited about the Canon Rebel Xsi 450D due out here in the next couple of weeks? I think I'm going to go hard and pay the bucks for it as soon as it hits the shelf. Canon totally hit the nail on the head by adding live view, IS to the lens (instead of the body) and ext. dynamic range! Not to mention boosting the megapixels to 12.2! What do you think? Or is the older Rebels still a great purchase?
