Sony Computer Entertainment Ireland MD Niall O'Hanrahan has said the success of the PlayStation 3 is not a done deal.

ps311 - PlayStation 3 is not the sure-fire...

Speaking to the Irish Times, O'Hanrahan has declared, somewhat contradicting what has already been said by Sony, that the next-gen console war is far from over, and Sony's success with the PlayStation 3 is not as certain as other Sony bigwigs would have you believe.

"We have a marketing challenge from now until launch. This is not a done deal. It will require a lot of effort from us," O'Hanrahan told the Irish Times. "We would never say we cannot fail."

O'Hanrahan isn't just concerned by the Xbox 360 and the Wii though, noting that "competition is now not limited to direct competition. We compete with MP3 players. We noticed at E3 that games for PCs are back."

PC games may have had a good E3, but the PlayStation 3's main rival is surely to remain the Xbox 360, with the Wii's low price ruling it out as a direct competitor.
