Sony won't ever admit it's programming a price cut and when, it would kill sales before it.
Edit:
@hotrodx:
I agree about March 2009 leaked or simply commonly predicted cut damaging current PS3 sales.
About Sony strategy, I think they're sticking on following their timeline without directly reacting to MS' moves, as MS would just hope for it as it's currently leading the game (at least for 2nd place sake) and a direct and predictable Sony reaction would be the best for MS interests.
Sony couldn't do anything for this Xmas anyway, it's too late to increase production and shipments enough to fully exploit a conjectural big price drop, the best they can do now is to sell out all units produced for Xmas and negotiate much lower 3rd party supplies' prices restarting production in the dead period after holidays, while ordering extra supplies now their price could even be driven up and possibly result in shortages anyway.
