The New Canon rebel xsi is here (this makes your XTI trash.)
it includes liveview, a 12.2 megapixel sensor, 14 bit processing and raw,3.5 fps continuous shooting, a 3 inch viewfinder, longer lasting battery, and sensor cleaning,
one of the best improvements is thicker materials. I picked one of these up and it doesnt feel as cheap and toy like as the xti did.
price is the same as always: $799 for body only and $899 for the body and the kit lens (18-55mm IS lens)
