Mario Wynands recently sparked debate when he claimed the Wii U was in serious trouble, adding that the next-gen of consoles - namely PS4 and Xbox 720 - are heading for failure.
Speaking to NowGamer, he added that he believes at least one console manufacturer will drop out of the console market before too long.
When asked on what Sony or Microsoft can do to improve the chance of success for the PS4 or Xbox 720, Wynands told NowGamer a "radical change" was needed.
"I’m not sure I know the answer here," said Wynands, "because the challenges they face seem to me to be insurmountable.
"Certainly, radical change is required and the solution is not in the details of performance and specific technical features."
Wynands added that - though the next-gen consoles are much more powerful - there is very little difference between the user experience of current gen or next-gen platforms.
"As it stands, there is already little meaningful difference between 360 and PS3 in terms of the consumer experience, despite the radically different architectures and approaches.
"For both retail and digital, Sony and Microsoft have to make it easier to get content on their platforms via streamlined processes, open up to a wider range of developers and publishers, allow a broader set of monetization options."
Wynands claimed Sony and Microsoft's biggest challenge is the need to sell a lot of hardware, but can't due to the failing retail industry.
"They have to sell a lot of hardware (obvious perhaps, but not easy)," he said, "and they really, really need to get behind digital in a big way to offset the retail rug being pulled out."
