Numbers are solid without a doubt, yet few things need to be taken into consideration. This Game was one of the most hyped Games this generation, Many PS3 Fanboys were claiming that this will be the turning point in fate of their console (another one lol) when Sony will capture the casual crowd and start crashing the Wii, we've seen loads of threads like LBP will sell 5,7,10,15,20 mln this generation, and will become a Mario Killer and defining title for the PS3. Also that the Japanese market will love it, we have seen it all.
Another thing, Sony really marketed this game Hard with Ads on TV, on the Street and with images of Sackboy in various media (Jonathan Ross TV Show for example). And Bundling it heavily.
So without a doubt this game will make a nice profit, but it wont be a defining moment for Sony like many claimed.
