Bodes well for us DSGers, i'm not overly fussy but equally it does matter to me that i'm getting the best from the car when required ie on long motorway journeys, i've said before if i get simlar mpg from the mk7 dsg that i do from my manual mk6 i'll be very happy taking into account the start/stop etc.
Stop start depends a lot on how long you stop and for how long. Audi brochures claim up to 3% saving (presumably for worst case city driving). If the stop-start is coming on a lot for you, you'll not really be in a position to be getting great mpg anyway. It annoys the hell out of my dad, and will probably do the same for me. If I can permanently switch it off with VCDS then I will, rather than remembering to switch it off every journey. It can never anticipate whether you are literally going to be stopped for 2 - 10 seconds, or 1 minute, and when it cuts out when you are literally about to move off again, then it is annoying.
If you expect 40mpg with a manual and 36mpg on a DSG driving reasonably economically most of the time then you'll not be disappointed. You can see from the CO2 values that the DSG will be 10% thirstier than the manual.
