We're betting that automakers are getting plenty ticked off at the European Trademark Office, because it seems that bureau has more leaks than a colander. Following leaked drawings of the new Mazda MX-5, Mazda3 and Suzuki Kizashi, the latest to slip out appears to be the upcoming Nissan 370Z Roadster. Of course it's no surprise that Nissan is preparing to launch a convertible version, since the previous 350Z made for a very handsome roadster, and even its premium stablemate, the Infiniti G37, has now spawned a convertible version. But this would be our first glimpse at the shape the new Z-Z-Topless will take.

From the leaked process renderings, we can see that the 370Z will keep a soft top like its predecessor, rather than go with a retractable hardtop like the Infiniti. We trust the roof will be less leaky than the European Trademark Office, though. While the 350Z Roadster had a sloping rear deck, the new version appears to be more bulbous. Which looks better is a matter of taste, and this writer at least liked the old one, but we'll reserve final judgment for when it appears in the flesh at the New York Auto Show in April.
