It might not be rational but it sure happens a lot. Are sports teams to blame when their fans go and riot, weather they win or lose? Do the people waiting in line for a movie for days have a valid case against the movie studios? Tickle Me Elmo, nuff said right there.
I didn't see any riots over the star wars movie launches... Even the Xbox360 launch was pretty low key...
Flameduck is right IMO. Sony fell short purposly on this. 200 million GTA fans are going to get to those systems the only way they know how (from the game), riots and shoosting!
