I figured A was most likely a placeholder that never got deleted. I just thought it was odd though that the price changed on that listing a few days after I ordered one. Mostly though, I just wanted to make sure that there wasn't a limited edition coming, or (even worse) a separate release for each language option.
A appears to be a duplicate listing that hasn't been removed yet, while B is the real listing. B is actually listing a product to add to your cart for pre-order, while A is just listing a price and no product.
edit: It looks like it also dropped to $16.99 tonight.
