Hllo People... I want to get myself a new camera.. I currently own a Rebel XT, but for some reason.. the foucs is acting a bit weird.. my pictures dont quite look as sharp as before.. so I was thinking on getting the XTi.. ( some of my work gets to be printed very big.. more than 20 x 24 ) but I dont want to get it.. and then.. a month later learn that a new model just came out.. everytime that I can.. I try to buy the product the first week on the market.. ( rebel XT / iPhone ) bought those the first day! .. so do someone can speculate / guess or whatever it is about when a the new model is coming out! Thanks!
