What's insane about this theory? These things are cracking left and right in multiple locations! Nintendo has also said yellow screen is a part of the touch screen technology, I wouldn't put my faith in their answers.I don't have proof from God of this or anything, but some of the speculative theories in this thread of what's been causing the cracks are ridiculous. Fer instance - just a couple posts back someone insinuated they used cheaper plastic in the first USA batch than in the Japanese models.ÂÂ
