With that information, and the fact that the E55 is consistently within .2 seconds to 60mph, (based on numerous U.S. car magazine comparisons of the two cars.) BMW will surley up the power of the 5 liter V8. Like they did when the E500 started getting close to the 3.6L E34. BMW responded with the 3.8L
I saw that BMW made a concept X5 (for the Geneva auto show I believe)with a 600+ HP V12, that was based on their championship winning Le Mans cars. Perhaps BMW will someday put that monster of a V12 in the M5. Along with suspension modifications, and many other extras. That would definetly leave the E55 in a large cloud of smoke.
