Will Sonic ever go away? No, probably not, as long as he keeps making SEGA money, much to Sonic Team's own chagrin. With that in mind, we can simply hope for the best as further information about the upcoming Wii-exclusive title, Sonic and the Black Knight, comes to light.
The deathmatch mode would be awesome if it was a huge open areas which you would have to dash at your enemies at top speed a slice them.
However Sega will probably make it close range with no speed...
Sonic is such a good character, but has developers that absolutely despise him. Sonic deserves a passionate team to give him the respect that he deserves.
