@Gnizmo : If Sony REALLY expected to sell more than 3 to 5 millions lifetime from a new IP from a declining genre from a small unknown independent studio, then they were really crazy... I don't think they ever told they expected to sell more.
There's no way a new IP will sell more than Halo or GT... Not a chance. I mean, that's the most they could hope really.
How many games sell 3 millions on the HD twins by the way ? Very few new IPs ever reach that number...
Media Molecule has like 20 members if I remember correctly, the profit from LBP sales must be really huge now. I doubt they're crying on their way to the bank.
