PS4 definitely isn't dead in Japan. It's just overdue for a permanent price cut. It's still selling for ~$270. It really needs a cut to ¥22,999 (~$210.)
Didn't they last cut the price in Japan just half a year ago?
In any case, PS4 needs a pricecut, not just in Japan, but worldwide.
Not sure when the last time they did a permanent cut, but since it still selling for the equivalent of $270, it's still too expensive at this point in time. As sales during the holidays prove, there are still plenty of people out there who want a PS4, but can't afford $270 & $300.
I do agree it needs to be WW. Though, I think Japan probably needs it the most. PS4 was only down 4% on a weekly average in the US in Jan. Not bad for a system that is going on 5 1/2 years old and still being sold for $299. When they do cut, I think it needs to be at least down to ~$210 in Japan and ~$250 in other parts of the world.
