Keep in mind this is for Europe only (hoping that launch date is later than the US/Japan one ) and not 100% official (trade magazine, not Nintendo themselves) so it may be wrong. But it's the closest thing to a date/price so far.
I did a quick check and £149 ~ $180. So a $200 or less price point seems really likely.Nintendo will release the Wii in Europe by 24 November for £149, according to games industry trade magazine MCV. The paper also claims there will be enough consoles to cater for demand both at launch and during the busy Christmas period.
The release date seems wrong in the "we will launch before PS3" aspect, but then again, it's Europe so maybe Nintendo doesn't have a worldwide simultaneous release with this.
