The raw power behind NVIDIA's soon-to-be ubiquitous Tegra II chipset makes for some interesting possibilities when it comes to gaming. However, there are certain pitfalls when one manufacturer leap-frogs the competition. Being the first to market in this latest generation of system-on-chips, NVIDIA has developers and exclusives pretty much at their beck and call. Who are you doing to develop for, the company with a multitude of devices hitting the market right now, or the "other guys" without any firm release date? NVIDIA's in a strong position right now, and it's going to do its best to solidify that.
Some of you may recall the stunt NVIDIA pulled with their PhysX engine, essentially crippling graphics on hardware without PhysX enabled - namely their ATI rivals.
