Microsoft's Xbox Live Marketplace website has some surprisingly impressive screenshots of Sega's upcoming Sonic the Hedgehog 4: Episode II that are leaps and bounds above the comparatively simple visual style of 2009's Episode I.  Perhaps the creative team behind these downloadable releases has been paying attention to constructive criticism after all because some of what I see here looks like it's on par with last year's Sonic Generations in places.  Check out the the detailed character models!  Marvel at the lighting!  Swoon at the the textured objects!  This looks downright gorgeous and probably explains why a Nintendo Wii release isn't happening for this installment (every other current platform will see it though; it's coming to Xbox Live Arcade, PlayStation Network, iOS, Android, Windows Phone 7, and PC).  Episode II is expected later this year, but if the game plays as well as it looks, then its release can't come soon enough.
