The circle pad, while nice, I don't think is super necessary. There are like 3 titles that support it, and if the title doesn't support it, you can't keep it on because of something stupid Mzo mentioned in the podcast that still hasn't been published. Also, it's only available at Gamestop, which seems silly for Nintendo to make such a necessary accessory only at one shop.
That being said, as soon as you buy one, the new one will be announced.
