Sony's Future Analyzed - PSX, PSP, PS3?

Thanks to an anonymous reader for pointing to Gamesindustry.biz's analysis of Sony's game console brands, called 'Playstation: Evolve, Multiply, Conquer'. The article starts with the statement that "Sony clearly sees the games market as a stepping stone to dominance of the home entertainment sector", and goes on to look at the 'Playstation 2 Plus' PSX device unveiled this week, as well as the newly announced PSP portable. The piece concludes by looking at what the Playstation 3 might be, suggesting a family of complementary games consoles may be Sony's eventual goal - "..in an ideal world for Sony executives, the question asked when you go to buy a new piece of consumer electronics will not be whether you want a PlayStation, but which PlayStation you want."
