Large Audi's should always have auto gearboxes anyway as the buying public and fleet will always favour them, no one goes 'hooning' around in them. The gearbox I linked to is MQ which means it is for transverse platforms only anyway. However there is also some cutting back on options Audi are doing which has nothing to do with other markets as it is across many of their models. I am sure they dropped the manual gearbox from the S3 because the clutch was the weak point, judging from owners reports in this forum.
If you wish my personal opinion the dsg, or the zf hp8, is perfectly suited for high performance cars, a non manual works fine in F1 and other motorsports and has quicker acceleration as well...
Funny how many US based car websites are also reporting on this gearbox
