Why have SCE Japan Studio developed another horse racing sim for PS3?

[FilaBrasileiro]

I really wonder what SCEJ is doing besides TRICO and GT5, maybe helping with Home? Maybe PS2 SE? They have really frustrated me this gen. Kaz should also try to bundle a family pack with MNG5 and/or Ratchet and a BD movie to go with LBP and GT5 bundles.
