"We believe that peak industry sales will occur in 2010, given that Microsoft will likely introduce its next console that year and Nintendo will likely launch before then," Wilson told GameSpot. "Further, 2010 is also likely to coincide with the end of the Nintendo DS and Sony PSP cycles."
The 360 and Wii were released in late 2005 and 2006 respectively, pinning Wilson's projections on a four to five year product life cycle for the consoles. Wilson made no projection for a PlayStation 3 follow-up, owing perhaps to the high costs of the PlayStation 3 and Sony's projections of a ten year life cycle for the console.
