i agree with the OP, i dont see Sony releasing a PS4 to compete with a new Wii. espeically since the consoles' features like 3D and blu ray are still relevant in todays market. some users havent upgraded to HD, yet alone made the jump to 3D. so i think the PS3 is able to hold its own in the market for a long time. i can see Sony pricing the PS3 at the $300 price point when the Wii 2 launches.
i think Nintendo are trying to force Sony and Microsoft into releasing new consoles.
if it was the PS3 alone, Sony wont release again. but the 360 is on the ropes in EMMEA and it has kicked the bucket in Japan. consequently lagging worldwide. so its possible that Microsoft will launch their new console in 2013 a year after the WIi 2.
theres no way i can see the 360 going toe to toe with the PS3 and Wii 2. so i think Sony will release their new console based on when Microsoft releases theirs NOT based on when Nintendo releases theirs.
