What you have to understand is, no matter what, SONY LOSES.
They cut price:
HAHA!!! They're doomed!! They'll just bleed money now! This is the end of SCE.
They keep the price up:
HAHA!!! They'll probably sell 4M consoles for the rest of gen! Come next gen the PS Brand is DEAD. This is the end of SCE.
