In Japan, currently there is only one model of PlayStation 3: The charcoal black 500GB version. That console's days are numbered.
The model number for this particular PS3 hardware is CECH-4300C, and it went on sale in 2014. There does not appear to be a replacement for this in the hardware line up.
Former Sony exec Ken Kutaragi previously said that the console would have a 10-year life cycle. The PS3 launched in November 2006, and now that it's 2017, you could say the PlayStation 3 has held on longer than expected. Thank revamped console iterations and an impressive game library for that!
No word how this impacts North America or Australia. Kotaku followed up with Sony, but did not hear back in time for publication.
