There’s been numerous rumours in the past surrounding a PSP2 from Sony. Many thought that Sony’s next portable device after the PSP 3000, aka PSP Brite, would be the PSP2. Instead we found another “PSP1 model” to complete the range of PlayStation Portable devices, the PSPgo.

EA recently revealed in an interview that as developers, they had gained early access to the next gen portable gaming device from Sony. Patrick Soderland, Senior VP has added that ” “Obviously as a developer we have had that access but, I’m not allowed to talk about it.”

As a part of its latest promotion plans, Sony is offering discounted and free titles on the PSP. As a part of this deal, games in the “Favorites” line will be available at a price of $9.99 and those in the “Greatest Hits” line will cost $19.99.

Sony has revealed the first set of titles in the “Favorites” line that will be offered at a discount. This list includes Ape Escape: On the loose, Twisted Metal: Head On, Syphon Filter: Logan’s Shadow and LocoRoco 2 amongst other games.

Sony’s PlayStation Portable first made it’s entrance to the market five years ago, on the 24th March. It become available in the US then and saw release to other parts of the world shortly after. Since then, the PSP has seen several make overs. The original 1000 series is now referred to as the “phat PSP”, ever since the PSP 2000 series, aka PSP Slim was launched in 2007 making the portable device 33% lighter and thinner. Shortly after, in 2008, we saw the release of the PSP 3000 series, aka “PSP Brite”, which had an LCD screen with five times the color contrast ratio. Sony’s latest PSP offering came in the form of the PSP Go in Fall 2009. The PSP lost it’s UMD drive and instead, titles can be downloaded from the PSN Store. Currently there are more than 520 UMD titles and over 300 titles on the PlayStation Network.
