It's quite a different story for myself. The more that I hear about fuel standards and the like, and GM's lost hope in Zeta, my interest particularly in Zeta as a viable platform for a slew of great rear-drive performance cars with exceptional performance and handling dwindles little by little.
It's quite frustrating really. I want to see this platform happen and come around full circle. I want to see it's basic concept and premises stay at GM for a very long while. I want to buy one, drive it, then trade it in and replace with a brand new one like what I had when that time comes.
See, what I can't quite wrap my head around is that GM just simply cannot make a platform with Zeta dimensions acceptable in weight and fuel economy. There are ways to do it (like using lightweight materials for the hood, or the roof panel, for example). Yes, I'm aware of the reality that a large, rear-drive car won't get the mileage as say a small European compact with a diesel. But there are ways to achieve respectable numbers with such a car of the Zeta's magnitude. (And it would also help if the U.S didn't use such inferior standards for MPG ratings, but that's different $h! to jaw about for a different day and time.)
I don't think GM's answer to every rear-drive enthusiast lies with Alpha. I can sit here and tell you that it just doesn't seem to ... click with me like Zeta did when I was first reading the news about it. I'll admit, it does sound like a nice platform and all: rear-drive, high zoot engines, plenty of pep, superb handling, good gas mileage ... but what about practicality? The Alpha's smaller size means a lessened degree of practicality compared to Zeta. I like Zeta because it offers me everything Alpha does and more (although, yeah, it's not as fuel efficient, I know). It had traits I wanted in the near future and distant future in a new car. It would have very well made me a GM customer for, literally, my entire lifetime. Chances are, I'll have kids in my thirties and, c'mon, thinking sensibly here an Alpha III sedan debuting in that particular time frame in my life probably won't allow me to have my cake and eat it too.
And that opens up another particular can of worms. It's starting to make me think that GM doesn't try to diversify it's product portfolio as much as it possibly could (i.e. meaning offering alternatives in house in order to make sure potential GM customers buy a GM product; ok, you didn't like the new Impala because of it's front-drive layout or this Alpha sedan here because of it's size, but can we interest you in maybe this rear-drive Pontiac sedan that's the same size as the Impala, and offers just as much content and comparable fuel economy, and has the rear-drive layout you favored so much with the Alpha sedan?). In a lot of ways, the old, dumbassed GM is still a part of the show, letting "customer surveys" and "market research" and internal politics and a moronic doomsday mentality in light of new government regulations dictate what cars it makes and not doing anything particularly new or particularly better than anyone else.
