Peter recently gave the game's demo a whirl and came away impressed. He found "a ton to admire" and said it was "full of impressive physics that make for an elegant and somewhat addictive experience." He promises more on his experience with the game later, so that's all he said for now.
If you're interested in more from EA, like NASCAR Kart Racing, he goes on about it later in his blog post. Check out the full post here.
