Considering that the S2000 is now a 6-year old vehicle, I should hope the Sky outperforms it. I doubt it will have that "track ready" handling the S2000 is known for, however. Isn't the Skye supposed to be the comfort-oriented version, while the Solstice is the more sport-oriented version?
I really like the way the Sky looks, I just don't think I could ever buy a Saturn. I've had friends who have had terrible dealership experiences with them, and the Saturn name just screams "low rent" at me. Use the Solstice's suspension tuning, the Sky's sheetmetal, and an Opel badge, and I'd buy one.
