Bashing Nintendo won't stop if Wii U doesn't improve. Wii U is a bigger investment for Nintendo, and it's the most worrisome thing they have now. Despite 3DS selling amazingly well, Nintendo still reported an operating loss at the end of their fiscal year. In other words, 3DS selling well will NOT enough to stop most Nintendo bashing. We need Wii U to fix this issue, because reporting operating losses from Nintendo is NOT a good thing and is something that many can easily bash.
Maybe you're trying to say that people will stop bashing Nintendo's handheld division?
