Kotaku just picked up the story from their sister blog (both Kotaku and Gizmodo are on Gawker media networks), and added this input:
"Super Monkey Ball and caveman karts are all well and good, but this looks like exactly the type of game I'm looking for on my overly expensive Apple product."
I wholeheartedly agree (even if it isn't QUITE as expensive anymore)... and with the SDK apparently being such an easy dev tool, I wouldn't be surprised if we saw a lot more games like this before '09 is over. Considering the games will be sold over Itunes as well, i wouldnt be surprised if Steve Jobs already HUGE pile of money doubles in girth in the next couple of years.
