Former Sony Computer Entertainment executive vice president Phil Harrison admitted in an interview that the PlayStation 3 may not be as successful as its predecessors as rivals are much stronger these days. To date Sony is estimated to have sold 41.3 million PS3 consoles, fewer than one third of the PS2's 147.6 million units.
Just eight or ten years away Sony had to ensure that it had a significant number of exclusive game titles to attract attention to its console. The competition from Microsoft and Nintendo was not too significant as both struggled to deliver high-quality titles. Both Microsoft Corp. and Nintendo have radically more advanced offerings than back in the PlayStation 2 era and ex-executives of Sony admit that the PS3 may not win this round.
"I hope PS3 can match PS2, but I think the market dynamics are slightly different. It is much more competitive. For a large chunk of its life cycle PS2 did not really have any competition anywhere in the world, so Sony was able to sell a huge number of units. If PS3 does reach the same level it will take longer and it will be a more difficult challenge," said Phil Harrison, the former executive vice president of Sony Computer Entertainment Europe, in an interview with Eurogamer web-site.
