There are several exclusive PlayStation 4 versions and designs around.

There's a glacier white PS4 console bundled previously with Destiny and announced to be available as a standalone console. Now, there'll be a silver PlayStation 4 with Dragon Quest Heroes.

Sony showcased the PlayStation4 with a silver slime on top at the Tokyo Game Show. The limited edition console was launched for the upcoming game Dragon Quest Heroes but it seems to be available only in Japan.

Reports suggest that the console aims to boost sales in the PlayStation 4's home country and the title is one of the biggest hits in Japan since it was released.

Dragon Quest Heroes comes out in Japan in the coming spring and the limited edition PS4 may also be available by then. Square Enix has not announced any launch plans for the silver PlayStation 4 in countries other than Japan.

Meanwhile, PS4 users have already enjoyed using the PlayStation Now and PS3 users can also enjoy the cloud streaming, Gaikai-based service in the U.S. and some areas in Canada.

Sony announced on the PlayStation Blog that the Open Beta will also be available to PS3 so users can play games without having to install or download them. The PS Now game database includes more than 150 titles with three games (God of War: Ascension, infamous and Ultra Street Fighter IV) joining the library.

Developer Konami also unveiled the Metal Gear Collection 2014 but not many people expected to see a clothing line inspired by it and even a white Metal Gear Solid 5 edition PS4.  Game director Hideo Kojima teased the white console several weeks back.
