long legs means low revenue most of the time because sony sells their games most of the time for very cheap only half an year after release or even earlier (with 19.99 official price, there is not much left) so a big bang at release should be much favourable to make money. that doesn't really count for nintendo with awesome legs and with high prices even after years for some games.
with that said, i don't think psabr will be a major "flop" like some other games for any console but after all that hype in any forums it still shows that internet world is really different to the whole gaming world. if you would only count the internet hype it should have had one of the biggest launch ever but nobody should have expected this and i think nobody did.
