The main reasons for people believing the playstation 4 release date is so far away are: The PlayStation 3 hasn't been on the market for long enough to bring in a new console. The technology isn't advanced enough to bring through an entirely new console. The cost of engineering a console that is significantly different may be impractical. But according to Sony there is significant room for overlap for the PlayStation 3 and PlayStation 4 to be on the market at the same time. The PlayStation 3 will be significantly reduced in price, whilst the PlayStation 4 will be significantly higher. Although costs will be astronomical to manufacture and ship two types of console, Sony has to be seen as keeping up with technology in order to be a leader in this fast and pacey market.

Sony confirm there will be a Playstation 4, although this is not expected to be released until at least 2010/2011. With the vast leaps in technology, the 10 year plan has had to be revised. With technology advancing so fast, to release a new console every 10 years or so is suddenly not a possibility. As ever rumors are flying around the internet as to what the PS4 will look like, as to what features the playstation will have and of course the cost of owning one. Some rumors include touch screen technology, holographic technology, 3D gaming, 3D motion control with sensors on limbs and people are even going as far as to say mind control technology!! The definite upgrades in technology will be Hard Drive Capacity, Blu-Ray upgrades, Processing speeds and the normal upgrades you will get with any console. Sony spend over $3 Billion in developing the PS3 and debates are being held whether the PS3 will be recycled so to speak with the upgraded technology inside. One thing is for sure though the more advanced technology used, the more pricey this console is likely to be.
