The all new M279 6.0L V12 biturbo *pictures*
I hope you didn't hold your breath for this one. Nothing new on the surface except for a matte carbon fiber cover instead of a glossy one... 
From what I could see, airboxes, throttle body and intercoolers looked the same as the M275.

So whats the deal, same displacement but a new motor design and designation M279 as opposed to the M275? The Hp is up a few but torque the same just matched with a 7 speed tranny? Is that at the Jacobs Javits Center already, you don't mess around. I wonder if a tranny swap is the next step in a modded 65.

Yes this is the at the Javits center last night, the gentlemen in the black blazer on stage is AMG's CEO
Well, I am surprised they called it an M279 when it's actually an M275 with some upgraded parts. The only thing that's changed externally is a matte carbon cover and a yellow plug where the dipstick would go.

Here's more about the new M279...
The AMG 6-litre V12 biturbo engine with the designation M 279 is based on the M 275 engine used previously and has been comprehensively revised for the new SL 65 AMG. New exhaust gas turbochargers with an increased spiral cross-section, new manifolds and wastegate ducts with optimised flow characteristics increase the engine output by 13 kW (18 hp). The multi-spark ignition with twelve double ignition coils not only results in smoother running, but also enables even more effective combustion in combination with a new engine management system with higher performance and optimised cylinder heads. The resulting reduction in exhaust emissions is also due to a large extent to the optimised catalytic converter system. The newly developed AMG sports exhaust system, which has a pipe layout with enhanced flow characteristics, is 3.2 kilograms lighter as a result of a reduction in the wall thickness.
But it is not just the inner qualities of the AMG 6-litre V12 biturbo engine that impress. The powerplant's looks are as inspiring as its performance: the high-quality carbon-fibre and aluminium engine cover reflects the exceptional character of the powerful twelve-cylinder unit.
For the first time AMG has combined the 6-litre V12 biturbo engine with the AMG SPEEDSHIFT PLUS 7G-TRONIC. The seven-speed automatic transmission with its wide gear ratio spread enables a significantly lower engine speed and helps to reduce fuel consumption. A new fuel economy torque converter, bearings designed for reduced friction loss and the transmission-oil thermal management system are responsible for a further increase in the efficiency of the power transmission system.
The AMG SPEEDSHIFT PLUS 7G-TRONIC has four different driving modes - Controlled Efficiency (C), Sport (S), Sport plus (S+) and Manual (M) - which can be selected at the push of a button on the centre console. In "C" mode the ECO start/stop function is permanently active. The compelling, dynamic character of the driving experience is made all the more vivid by the automatic double-declutching function during downshifts and through the brief, precisely defined interruption of ignition and fuel injection during upshifts under full load; the latter functionality has the additional benefit of reducing the shift times.

I asked one the the two people onstage if they had fixed the notorious V12 coil pack problem and I was told "not yet."
Thus the press release account of the system is problematic and leaves questions since I am not a V12 maven. Does anyone else have a clearer idea or information?
