That is just an estimate. Most people are assuming $199 though at this point. They seem to be aiming to get 3rd party support for the first time in history. So I’d imainge there will be some damn good games, especially given how cheap the dev kits are.
They are also there area some odd hits that they might support more independant developers on their website too. I’m not putting much faith in that based on their history.
Regardless I definatly am planning on getting one.
