Sony predicts that the PS4 will eventually outsell the PS3 when it is all said and done.
Sony Andrew House was interviewed by MCV and he said that the PS4 has an opportunity to the PS3. He said the main reason is because of the low price point which is more “consumer friendly”.
The PS4 is already off to a hot start already selling 2.1 million units worldwide. The PS3 has sold over 80 million units so far in 7 years since it was released in late 2006. I’m guessing the PS4 will be able to exceed it too since the PS3 scared a lot of consumers at the start due to its high price.
The two most successful Sony consoles have been the PSOne and PS2. Those consoles sold 100 million and 155 million respectively overall.
