"..Sony is planning to update the PlayStation 2 rather more quickly than that machine will supplant the original PlayStation. The gap between PSX 1 and 2 is five years (1994 to 1999), but according to Kutaragi's presentation, the PlayStation 3 could appear in three years' time -- just two years after the debut of the PlayStation 2.

The next-generation of Sony's Linux-based PlayStation development system is due in 2002, and it too appears geared to tie in with the release of the second version of Emotion Engine and PlayStation 3. Sony is describing the system not only as a video game development system but also as the basis for creating real-time digital entertainment content.." NULL
