Will the upcoming Rapide (S) get the new V12 from the Vanquish?

Last week I already posted spy shots of a possible Rapide S. And today, both Autocar.co.uk and Leftlanenews.com came with more rumors about this future Rapide. Both sites claim that next year’s Rapide will get the new V12 from the Vanquish. Which means it may get up to 565hp, but it also possible that the engine will be downtuned somewhat for the Rapide. The question still remains: will this just be the new MY2013 Rapide, replacing the current Rapide, or will it be a new Rapide S model, positioned next to the Rapide. Currently my guess is that this new Rapide will replace the old one.
