A couple points
First, it's not so much the first week's bump that matters it's the sustained rise in sales from WSR that'll be important.
If Nintendo wants new casuals to notice WSR then they need to take to the malls again and get people to try WM+. People without Wii's just assumed Wiis worked like that all the time though.
I suspect NSMBWii will probably do more to boost sales than WSR but this year Nintendo has really done themselves a disservice by not further exploring the blue ocean. All titles are red ocean sequels. And again Nintendo is not supporting it's own peripheral (WM+) with any other games this year.
I do think a Wii price cut as well as colours are very likely this year (and long overdue). I also think if both MS & Nintendo cut prices then Sony is still screwed despite any price cut and will remain last.
Lastly, thanks to WS and WF the Wii has a huge mature female market that noone - not even Nintendo - is capitalizing on. There's gold in dem hills folks! Once someone figures out how to mine it.
