Dismissing any possible scepticism over the technical gap between current and next-generation machines, Sweeney assures that the improvements will be significant.
"It's going to be a substantial leap over the current generation," he said.
Speaking during a presentation at the Montreal International Game Summit in November 2012, Sweeney cited huge costs developing the Samaritan Unreal Engine 3 tech demo, which took four months to finish with a team of 30 people involved.
Sweeney said he expects development costs "at the start of the next generation" to be around double that of start of the previous generation.
