The iPhone 3GS is already wooing game developers with its faster, more powerful platform, but don't expect a ton of games fully taking advantage of it to flood the App Store--yet.
Though 1 million iPhone 3GSs sold in one weekend, the latest Apple mobile device is essentially still a niche product, compared to the 40 million original iPhones, iPhone 3Gs, and both iPod Touch models already sold. And those won't be able to run games with the same efficiency and speed as the new iPhone 3GS.
In short, it's still too early to declare the era of iPhone 3GS games officially arrived. Some game makers are waiting, or not creating games to take advantage of the device at all. Some say it's "not wise" to play specifically to what is still a small slice of the audience combing Apple's App Store for the latest downloads. For example, Pop Cap, the company behind Peggle and Bejeweled for the iPhone, said its games are benefiting from the faster load times the 3GS offers, but it has no plans to create games that are iPhone 3GS-specific.
This wait-and-see approach may be contrary to what some expected. The iPhone 3GS was essentially an update to the iPhone 3G. The "S," we were told, stands for "speed." Indeed, there's a faster processor, a PowerVR SGX graphics chip that can handle 3D rendering, and support for OpenGL ES 2.0, a standard use for creating 2D and 3D graphics. It also has a magnetometer and a video camera, unlike other Apple mobile devices.
