true, true, but like all saturns, or GM for that matter.... the tame version comes, and then the redline/ss/etc..... if saturns future was secure, there would no doubt be a redline astra with close or the same power as the cobalt ss/tc (what like 260 hp?)
Perhaps, but I wouldn't bet on it. As it is now, Saturn only barely seemed to offer the Astra. In fact, for '09, they aren't even building any for the US and plan to sell through the existing '08's instead(
http://www.autoblog.com/2009/01/28/saturn-astra-disappears-for-2009/) They have one engine option and it's one that we don't even get in another US model. It's not a particulalrly fuel-efficient one either, not with the Cobalt achieving mid 30's MPG with similar HP yet the Astra barely ekes out 32mpg and with the stick shift only.
Also, in order to get the 3dr version, you have to buy the uplevel XR because that's the only one they sell you here and it's like $2K more than the 5dr. To make matters worse, that same 5dr is only available as the lower-lever XE model. Just makes hardly any sense to me. The cost really hurt it compared to the competition as well. I think they should have taken a cue from VW and sold the 3dr for less even if it meant taking a loss on it, just makes sense, not to mention selling both trim levels on both versions. Americans aren't used to paying more for a smaller car than a bigger one and at a $16,500 base for the 5dr(base model, mind you), they have a lot of other intriguing options.
Being a Euro model, GM had a golden opportunity to bring over some(or at least one) of their diesel engines that would slot right in and really have a car that gets great mileage. Then, they could have offered the diesel, perhaps an engine shared with the Cobalt for a better mileage gas engine, and a Red Line model and had pretty much anyone covered. They also should have offered any of those options with either the 3dr or the 5dr body style. Some advertising would have helped too. They did primarily online advertising for the Astra and no print or TV ads I believe.
As far as the future, who knows. With Saturn likely going away, I'm not sure I see a home for the Astra in the US. I think it could be a Pontiac, but with Pontiac skrinking too, that's iffy. I couldn't see it as a Buick and if it were a Chevy, it would be competiting with the Cobalt(or Cruze in a few years) and it would get outsold 3 or 4 to 1 with Americans preference for sedans over hatches. I guess it could happen though, but I'm not betting on it. Then there's also this news that came out today,
http://www.autoblog.com/2009/02/27/opel-to-spin-off-gm-will-retain-stake/ Who knows how that would affect things.
Work is well under way on the next Astra though and it looks nice with an interior influenced by the awesome Insignia Sedan built overseas(will eventually become our next Malibu and Aura if Saturn is around by 2012)

We'll first see the Insignia(or it's platform rather) as the 2010 Buick LaCrosse,
http://www.autoblog.com/2009/01/08/detroit-preview-2010-buick-lacrosse-breaks-cover/Here are a few shots of it. Believe it or not, it's a Buick I would actually not mind buying.



Also, here's the Opel Insignia built on the same platform which again will trickle down to the Malibu, Aura, and G6 if all 3 are still around in 3yrs or so.



That last interior pic is interesting as well. The instrument panel lights change from white to red when the sport mode is engaged. I thought that was a neat tweak that you don't see everyday.
In case you can't tell, I'm somewhat of a GM fan

I've been raised on them all my life.
