3.7 litre is not possible with the present FSI/TDI V6 engine line, they have a volume limit of 3.2 liter, otherwise Audi had increased the V6 engine volume of the 3.2 FSI and put it into the Q7 instead of the Volkswagen 3.6 VR6 FSI engine..
The V6 Bi-turbo FSI engine will have 3.0 litre volume and can be seen as the successor to the 2.7 litre V6 Bi-turbo S4/RS4 engine and will have between 320 and 350 bhp.
The S4 will keep the same 4.2 litre V8 FSI engine but will get most likely "Valve-lift" added to it with a 3-5% power hike.
For the new RS4/RS5/R8 engine Audi have 3 options:
1) The same 420 hp 4.2 litre V8 FSI engine. (RS4/5)
2) This same 4.2 litre V8 FSI engine with Valve-lift and ± 440 hp. (RS4/5 and R8 upgrade)
3) A 4.2 liter V8 TFSI with ± 470 hp. (RS4/5 and R8)

Ah, very logical suggestions there Hans - as usual.
We all know that Audi have a lot of urge in reserve for the S5's V8. With the discontinuation of the RS4, there's no reason as to why Audi can't boost the power of the current V8 to be closer to the, say, 285 kW mark. So, the new S4 could usher in this uprated V8 without Audi engineers breaking so much as a sweat. Heck, if we're really lucky Audi would be super clever and make the S4 pick up straight from where the RS4 left off. We all know that RS4 incarnations appear late in the model lifecycle in any event, giving Audi engineers plenty of time to turbocharge a V8 FSI.
Of course, your assertion about the 3.2 V6 being at the limit of its capacity makes perfect sense; that's why the Passat, Touareg, Q7 and Cayenne V6 all use the (much less sophisticated) narrow angle VR-type V6 engine which is now down to just under 11 degrees angle between the two cylinder banks.
As for a twin-turbo'd B8 with 40:60 quattro - ooo - too nice to contemplate!
