In their first two years on sale, Ubisoft expects the PS4 and Xbox One to sell double that of their predecessors during their respective launch periods.
Console launches in recent years - including Nintendo's 3DS and Wii U, and Sony's Vita - have suffered slow starts to life. But Ubisoft seemingly expects no such issues with Sony and Microsoft's new high-end machines.
"As the industry transitions to a new console cycle, past market trends and Ubisoft's internal estimates indicate that within two years the next-gen consoles' installed base could double that of the previous generation over a comparable period," it said in a press release today regarding its E3 lineup, for which it has promised to reveal "exclusive next-generation games".
The firm says it's primed to take full advantage of the major console transition due later this year.
"Ubisoft's cross-studio collaboration structure allowed the company's creative teams to get an early start on the transition, with next-gen games like Watch Dogs already scheduled for release this year and more next-gen titles to be announced during E3," it said.
Company CEO Yves Guillemot added, "This is a pivotal moment for the video game industry, and E3 is the opportunity for us to share our vision for the future.
"We have many incredible games in development, and we're especially excited to share more on our next-gen titles, which will deliver more connected, immersive and interactive experiences to our fans."
Sony announced the PS4 back in February with a launch of 'holiday 2013'.
Xbox One was revealed at an event on May 21, when Microsoft confirmed a launch for 'later this year'.
