How Much Will the PSP's New $169.99 Price Effect Sales?

[Steve 3.2]

Now that we have a price drop (though less than many people wanted), what effect do you think it will have on the PSP's US sales?  Do you think this will have any repercussions on the Nintendo DS?  And should Nintendo respond?

I think the new price will improve PSP sales in April, but that they will return to their normal levels after that.  I don't think this will have much of an effect on the DS since Pokemon comes out this month and that game will sell systems all the way through the holidays.  I also think that we'll see the DS on top in sale for April.  And since the DS will continue to sell well and the PSP didn't drop to $150, Nintendo doesn't need to and won't respond to this change.
