Prediction: PS4 to sell a minimum of around 70% of its lifetime sells in the first 2 to 3 years in the market.

Nah.

The PS4 will sell really well throughout these first few Years but where it will really shine will be in the legs, just like every PS home console before it. The reason? Continued support.

PlayStation consoles have brilliant support later on because its a guaranteed userbase that will buy Millions, if not BILLIONS of games. Its selling on hype alone right now, with no real system selling exclusive to note. When these exclusives start to pop up and certain userbases are popping up in pretty big numbers, then they wont go anywhere fast.

Support = Sales

Sustained support = Sustained sales.
