SEGA has started a very familiar campaign called ‘Concept Art Friday’ which will see SEGA release concept art for Sonic the Hedgehog 4: Episode 2 every Friday on their blog and on Sonic’s Facebook page. To kick things off, SEGA has today released two images on their blog of what appears to be a wheel switch from Sonic the Hedgehog 3′s Marble Garden Zone and an image on Sonic’s Facebook page of a new badnik.

Check back next week for more. In the meantime, let us know what you think of SEGA reusing this marketing strategy in the comments section.

SEGA has just officially revealed Shadow the Hedgehog as the next rival character in Sonic’s upcoming 20th Anniversary title Sonic Generations. New artwork for the black hedgehog has been released showing him in quite the angry pose. No other details or screenshots have been released at this time regarding which stage players will battle Shadow. But with the Tokyo Game Show coming up this week, hopefully SEGA will release more info and media. We’ll keep our eyes peeled.

SEGA has today opened the characters section of the U.S. and European official Sonic Free Riders website, revealing new artwork, small profiles and a new music track from the game. The only characters unlocked at the moment are Sonic, Tails, Knuckles, Jet, Wave and Storm, but the website states more are “Coming Soon”. Thanks to Gamespot’s exclusive demonstration of the final build, we currently know of 17 characters, which include Metal Sonic, Vector and a blue E-series robot likely called E-10000B that are new entries to the series, so we can expect plenty more profiles to be featured on the site.

Check out the rest of the new artwork below:

Courtesy of Amazon.de, we can now see what the full Sonic Colours Special Edition looks like for both versions of the game and it appears it is actually called the ‘Limited Edition’, which of course means that only so many of these will be made available, so if you’re after one then you should get pre-ordering. The contents appear to be no different to the loose contents EB Games Australia revealed, but at least collectors can now rest assured that they’re not going to get lumped with the figure and Wisps being loose on the side. Also of note is some new artwork revealed on the side of the packaging, which includes a new render of Sonic. You can view that and the DS package below. If you’re in the UK, don’t forget that you can get this action figure and Wisps for free by pre-ordering either version at Argos.co.uk, who recently dropped their prices.
