Is a V8 w206 C-class possible?

With spy pictures of a “C63” that is wider than the normal w206 C63 questions have begun to emerge about what this could mean.  Is it just a reworked rear suspension setup for the upcoming “CLK/CLE” coupe platform?  Or is it possible with 670 hp the 4 cylinder C63 deserved the title, while the C73 will receive even more power and AMG v8?
