This is what makes the 500hp, 4k pound M5 as fast as mid-engine Italian exotic cars with as much power and much lower weight. The 7th gear is huge as you keep the engine in the sweet part of the power band alot better.
By the way, my current M3 is a manual. I just happen to like all the newer technology coming out.
It is not like adding another 100hp. The extra gear is simply an overdrive gear that allows for slightly more aggressive ratios where it counts.
The new M3 should have some pretty crazy gear ratios considering the flat torque curve and the massively high rev-limit (think of the high revving, low torque F1 cars. same idea). If you can really wind the engine up, then you can use the gear ratios to your advantage. Also, if you can make some decent power down low, you win on both ends of the spectrum since you don't have to drive at 3500rpm around town. A major draw back, of course, is the fuel economy, but BMW seems to be pretty sensitive to this hot issue these days, so I wouldn't expect it to be any kind of deal breaker for those in the market.
All in all, I'd like to say that BMW actually seems to know what they are doing after a period of some questionable decisions.
