Oh come on, its not so bad, yes it does look like the current SL, but that one will be replaced next year by a complete new one anyway, that probably look like the SLS, or the SLR SM (its beeing around for nearly 9 years, so it definatly will be replaced, rather beeing lifted again)
Also I have to say, it looks a damn side better than the old SLK, with it's silly F1-Nose.
Edit: Btw, by comparing the old and the new SLK, I see some fairly close parallels, which tells me that this new one, is just a Facelift of the old one.
