PS3 has reached 51.8 million units sold, Sony has revealed during its Tokyo Game Show press conference. Additionally, the PS3 has accounted for 49% of consoles sold in the last year since TGS 2010 and PS3 software has represented 46% of the market overall.
As for the PSP, Sony mentioned that it's sold 71.4 million units worldwide. It would be interesting to get a breakdown by region since the portable has struggled a bit in North America but thrived in its native Japan. In the year since last TGS, PSP has grabbed 43% of the handheld hardware market and 46% of portable software.
PSP remains popular in Japan but it's probably about to take a back seat to the Vita portable, which launches on December 17 in Japan.
