The new car is likely to be called the 911 GT3 RS Limited Edition and will be based on the current 911 GT3 RS, except with a 4.0-litre version of the famous flat six rather than a 3.8. It will develop 500hp, and a run of 500 cars is expected.
The web rumour mill also suggests that the GT3 RS LE could mark the debut of Porsche's new so-called 'PDK-S' gearbox, a more sports-oriented version of the company's twin-clutch transmission, which is widely expected to be available on the next-generation of 911 GT3 models.
So is it true? Porsche, of course, is keeping shtum on the matter, so we won't know for certain until 7th April when - so word has it - the official details of the car will be revealed.
But it does sound like a believable - and deeply tantalising - prospect. Watch this space.
