One of the strengths of buying GM has always been that even if a model went out of production, parts for that model were shared across the entire product lineup and so you could take a part from a Buick and slap it into a Chevy without trouble.
It's the trim pieces that you'll have trouble getting, but those were expensive to start with and if there's a market, there should be aftermarket suppliers for a while anyway.
The only GM North America brands that don't use shared drivetrain parts with the rest of GM are Cadillac, at least for most of the engines, maybe some Saturn vehicles, and the Chevy Corvette, which is in a class practically by itself*.
Transmissions probably are interchangeable but I'm not certain.
*The Cadillac XLR shares a lot of Corvette parts and is in fact built at the same Bowling Green plant the Corvette is.
Also the CTS-V uses a Corvette engine.
If I had the bank balance to afford one, I'd buy a 2009 CTS-V before I'd buy a Lexus, Infiniti, or even a Mercedes.
The Corvette engine is an LS series engine. The ZR-1 excepted, the only difference between a mainline Corvette LS engine and an LS2 used in a car such as the Camaro are some power boosting enhancements (such as slightly different heads, IIRC), the exhaust flow system, and a "batwing" oil pan to allow the engine to be mounted closer to the ground. Other than that, people have taken Corvette engines, put normal oil pans on them, and dropped them into Camaros without much difficulty.
I actually took a complete set of seats out of a ~1999 Camaro and swapped them into my 1986 Camaro. The bolt patterns are identical, I only had to replace the wiring harness connector to get it to work. They're much more comfortable as well.
The 3800 V6 is another engine that wound up being used in almost every GM model until it was finally discontinued. It was based on the 1960s 3.8 V6 that was sold to Chrysler and then bought back in the 1980s and used in the Turbo Trans Am in turbocharged form, and in most of the midsize cars such as the Chevy Malibu and Buick Century. They stopped using it for a few years in the mid 1980s due to emissions reasons while they figured out how to convert it to fuel injection, and then reintroduced it as the 3800 in the early 1990s. It stayed in that form right up to last year.
As far as transmissions, I'm not sure what they're doing for FWD transmissions. Historically GM has partnered with Borg-Warner for its passenger car and pickup truck transmissions, and I don't see why they would have stopped that. However, for anything RWD, they have the 4L/6L line (the 4 and 6 referring to how many speeds it has). This line is a direct descendant of the 3 speed Turbo-Hydramatic 350 and 400. The 4L60 was one of the first of that line and came out in the early 90s on the F-bodies. The 4L80 was descended from the Turbo 400 and used on the truck models. As far as the heavier trucks go, they use Allison 6-speed automatics in them.
If GM kills Pontiac, that will be a sad day for auto enthusiasts as it would completely dash the hope of ever getting a Firebird again. I also wonder what they're going to do with the Solstice, as that was only being shared across Pontiac and Saturn (so far) and is a fairly popular vehicle as far as 2 seat roadsters go.
