MCV reports that Strategy Analytics analyst David Mercer predicts the PS3 will outsell the Wii by 2013. While he does leave some wiggle room in his forecast, “the signs are that the Wii has peaked in terms of console sales, and its installed base will begin to decline after 2011. Meanwhile, Sony’s PS3 and Microsoft’s Xbox 360 will continue to grow, so that the PS3 will become the largest platform globally by 2013. In terms of cumulative lifetime sales we expect the PS3 to hit 127m units; compared to 103m Wiis…Uncertainties clearly surround each of the major platforms, particularly relating to the new services and upgrades planned by Sony and Microsoft. Natal on the Xbox could be more beneficial to 360 sales than expected, and Sony’s own motion controller, together with its plans to upgrade all PS3s to 3D capability, also represent potential for upside to our core forecasts.”
