It turns out that the official GTA V gameplay trailer, which Rockstar spat out on Tuesday afternoon, wasn't running on either a special development box or some PC. No, it was the vanilla PS3 version on display.
You see, Rockstar decided to come out and clarify that what we saw was current generation, and not next generation graphics. So, there you have it. That gameplay trailer is exactly what you can expect when you finally crack open the box and thrust that Blu-ray into the slot for yourself. Roll on September 17th. [Rockstar via Ubergizmo]
