With all the recent rumours of PS3 price drops, VGChartz contacted SCEA for comment on the matter:
SCEA has no immediate plans to drop the price of the PS3 system.
As you know, NPD sales numbers for February will be announced today and will include Killzone 2 sales the first couple of days at retail. Given that the title launched so late in the month, we'll see the majority of sales in March. Killzone 2 experienced the highest presale numbers of any first party PS3 title to date and we anticipate that it will be a blockbuster for PS3 and the PlayStation brand."
So there you go, straight from the horse's mouth there are no PS3 price drops planned for the immediate future. This confirms what we've heard from other sources and VGChartz along with most major analysts expects Sony to announce a two-stage price drop for PS3 this year - $50 around June time and a futher $50 before the holidays. Stay tuned for more developments.
