Total software sales for next-gen consoles based on NPD september numbers

[Alvar]

Hard to compare when you don't actually know the average price per unit. I mean... shouldnt the 360 for example have more "cheap" titles considering it has been out a year longer? (Platinum series and whatnot)

And isnt Wii play (250k?) more than 50$? (I realy have no idea what the prices are in US)
