it's no speculation, there definite will be a successor to the 360. no major optical changes, though.
rennteam was informed very early, note this news:

the step from 348 to 355, in terms of look at least, was also more kind of a modificiata IMO.
the "420M" (or whatever it'll be called) will probably be introduced at the geneva show in spring 2004.
