I think Demon Souls is a bad example. Almost everyone on this site that hypes it have actually played it. Much like Valkyria Chronicles, it is an excellent RPG that happens to be exclusive to one console. I don't think anyone has stated that Demon Souls is a "game changer" or believes that it is a system seller.
My issue with your larger point is that everyone is guilty of hyping exclusives and ignoring multiplatform games. How many threads do you see about Forza, Halo, GT5, Killzone 2, etc. ? To claim that this phenomenon is exclusive to PS3 owners is unfair and untrue. Both Dead Rising 2 and Lost Planet 2 were hyped early until the PS3 versions were announced. I remember a thread hyping Banjo Kazooie and several regarding Lips. Rarely do you see anything regarding Modern Warfare, Assasins Creed, or even Batman (which released today).
Thanks for the input, Jeff.
