Because he does not appeal to most of sony's target audience and secondly because he has not had enough time compared to other platformer characters.
I liked LBP, but I only played them because the first came bundled with the ps3 and second was from PS+. I dont think I would have gone out and bought them.
I also think the fact that they said they wanted LBP1 to last the entire PS3 gen killed the hype for the next one which they still released on PS3 anyway.
