Pluto

Sega Pluto is an unreleased variant of the Sega Saturn. It was revealed by a former Sega employee on April 17th, 2013 on the Assembler Games forums, not much is known about the console. The Pluto was a revised version of the Saturn with an onboard Netlink modem, along with a new chassis and bodywork.

The system weighs in at a rather hefty 2.8kg and has two controller ports, a top-loading disc drive with a flip-top lid, and a cartridge slot. It was designed prior to the announcement of the Dreamcast. Six functional prototypes, along with several resin mock-ups that were showcased at E3 were produced. Four of the functional prototypes were destroyed, with only two currently remaining in the world. One of the two surviving prototypes was obtained in the late 1990s by Roger Vega at a flea market in Stockton. There is a YouTube video of this console being repaired by tech celebrity Benjamin Heckendorn.

In early 2015, a surviving E3 mock-up of the Pluto had turned up on eBay. The auction has since ended on February 23rd, 2015. Up until 2013, this image was thought to be the Blackbelt, one of the two console designs that were considered to become the Dreamcast, but in reality, it was actually an artist's impression of the Pluto.
