I guess they know something I don't. With the reasonably broad powerband of most gas engines it seems like overkill in my opinion. 6 gears seems to be a good number for keeping the engine in the powerband without being as complicated as 9 and 10 speeds. For diesels it makes more sense because of the narrower rpm band, though the current batch from the big 3 seems pretty good with 6 speeds as well. I suppose one thing it will do is give so many ratios only one rear end will be needed, heck they have almost done that with the 6 speeds. With gas engines especially, 9 and 10 speeds is almost a CVT, with more complexity.
