I think that Widescreen will win in the end. The main reason is HDTV(Widescreen TV's). Even though acceptance by the majority of consumers may take up to a decade, widescreen TV's will eventually become the norm for television sets. Hopefully this will happen sooner than later, but eventually widescreen sets and therefore widescreen DVD's will become the standard. Then people will probably complain when they buy a pan and scan or full screen version DVD and see the black areas on each side of the picture.
