I always forget with NPD is this units or revenue?

EDIT: This is revenue.  Not really surprised by that.   PS3 had a $50 price cut compared to last year. Wii had a $50 price cut compared to last year.  360 had some sales (I do believe that NPD does not subtract out gift cards).  Wasnt the PSP cheaper than last year? How about the DS line up.  3DS was what 169 and there were some sale prices as well.  So even with the same amount of hardware sold the revenue would be down.

Its libraries that sell systems not a single game.
