Until it's official, no different from blindly guessing at price before.
Several sites have the games up for preorder for $99.00. I'm pretty sure they're using placeholder prices and there's no real price given to them yet since doubling the price of games would be strange and uncalled for. Getting a solid release date is much easier for them since stores will have to know when to stock such an important seller and are given that info sooner than pricing. They set the price far higher than expected so they won't have to deal with customers if the price goes higher later. People complain about being charged more, not when charged less. Do you really think the first place they'd give a price to is Amazon Germany and not Japan or US sellers?
But hey, don't take my word for it. Actually find someone that actually can read German and visit the page itself. There's a disclaimer that states that it isn't the official price and will likely be lower. Bothering to fact check a site in a foreign language is apparently a step most journalists don't take these days. Good going.
