Microsoft says that the Xbox One is a 10-year console, but what about the PlayStation 4? We asked Sony UK boss Fergal Gara whether the PS4 is in it for the long stretch.
"I think there's reasons to believe that the next cycle might be shorter in markets such as the UK," he said.
"It's probably a sign of the times and how much has changed in seven years, but I think the willingness and the appetite to pick up new technology fast has probably changed quite a bit."
"What we do know is that the uptake [of the PS4] is going to be very sharp," said Gara. "Does that mean this is going to be a much bigger cycle? Maybe. Or it might mean that it's just a bit more compressed into the first few years, that the latter years are a little softer."
