Nintendomination is here to stay - for now anyway.
All we are seeing is "expected" increases in sales of all devices due to the Xmas season.
The real challenge for MS & Sony is to stay competitive once the holiday season drops off. Ninty won't have too much of an issue (WiiFit hits US just after the new year, and Brawl hits worldwide end of Jan).

The DS is outselling the PSP (the NEW model) by a ridiculous level - around 4:1 at the moment. Software wise, its much much worse. I'm predicting next year will be the last for the PSP - its going to be the first one to fall.
And the Wii is selling out - it physically just can't sell any more units at the moment. Its roughly selling what the (360 + PS3) do combined.
Based on the current front page figures - the DS + Wii currently have 65% of the total hardware market. For one company (out of three) to have 2/3rds of the total market - that is pretty close to domination!
