First up, legendary id Software founder and Doom and Quake mastermind John Carmack spoke to Forbes about iPhone gaming:
"We wanted to do something for the iPhone, but we just didn't have the scheduling or the resources available. I really regret not having something at launch. We have a title we want to develop exclusively for iPhone. I'm not announcing anything specifically, but it would be a graphical tour de force."
id clarifies it will be an existing property, and Carmack goes on to say the iPhone is Xbox or PS2 class when it comes to power, a little lighter on the graphics, but a lot heavier on the RAM, and when (and if) the business model makes sense, he could easily see spending $10M on developing an iPhone game.
Next up, TUAW covers the Torque Game Engine and its recent release for the iPhone. Torque would sit on top of the OpenGL ES system and help developers create better graphical experiences faster via their Game Builder software.
Lastly, Gizmodo shows some video of the updated NES emulator (for jailbroken iPhone's and iPod Touch) which adds accelerometer support for increased gaming goodness.
Me thinks iPhone gamers are going to see an amazing second wave of software in the coming months.
