I thought it was just another tiptronic-flappy paddle style set up. It's surely just a regular m3 box with automated change.
Tiptronic, manumatic, and other similar transmissions are one thing.
VAG's DSG, BMW's SMG, Ferrari's sequential gearbox, and any other sequential-manual are something else entirely.
Tiptronic- and manumatic-style tranmissions are just a standard automatic, but instead of shifting automatically all of the time, they allow the driver to choose his/her own gears. The result is somewhat similar to a sequential-manual's operation, but gear changes are very slow, acceleration response time is still slow, and many systems will switch back to automatic mode if you don't shift for a while.
DSG, SMG, Ferrari's system, and other such transmissions are a
true manual gearbox, but with automated gear changes and clutch engagement. The result is all of the positives of a manual transmission, but without the clutch, and with the option of an automatic-shifting mode. One drawback is that in low-speed, everyday driving, some systems such as BMW's SMG can shift very roughly, or screw up and shut down completely. BMW has apparently fixed this on more recent versions of SMG, but some car mags, such as Road & Track, are reluctant to try it again.
From what I've read, VAG's DSG is simply the best system out there, providing both lightning-quick manual gearchanges, and smooth, trouble-free automatic ones.
