Of course they will deny
Regardless of findings are, Intel will deny the above as fundamental design flaws. I doubt Intel will be punished with more than formal spanking, but even admitting the design had flaws means Intel's chips designers either completely ignored possible security considerations, or did not bother to look for possible security implications at all. If the same designers will fix the vulnerabilities, as Intel promises, guess what will can happen.
Congratulations, Intel. Since the notorious FDIV bug this "spectral speculative meltdown" is much more impressive example of epic fail.
I suppose no one from IT experts now has an illusion that Intel cares a bit about security.
