I imagine it'd be a good time off, but there could be some truth to Newell's words here. I'm not sure Apple's dedicated induction into the realm of "living room" gaming would ring the death knell for other console makers, but it would undoubtedly take a
HUGE chunk out of their user base and, consequently, profits. So while it wouldn't mean Sony, Microsoft, or Nintendo would suddenly go out of business, it could mean they might go the Sega route. Pull out of the console making business and pool resources solely for game development.
Or, he could be way off base and Apple may never attempt such a move. I don't know. That said, Gabe Newell has made many claims and predictions over the years and, while not always accurate, he's got a pretty good track record for guessing correctly.

I for one would like to see an Apple console. Though, I would have reservations when it comes to their traditional OS, which doesn't run DirectX, but OpenGL. But hey, that didn't stop the Wii, which is also OpenGL.
Accept that, generally speaking, OpenGL is superior to DirectX. In just about every way. (ignoring id's God awful snafu with Rage for a moment) Hell, OpenGL had tessellation
years before DirectX even hinted at it. The problem is Microsoft ran a rather successful "scare tactics" campaign against it in favor of DirectX. As a result many people, even some in the game design community, bought into the crap spewing from MS and have shied away from OpenGL for years. This has led to OpenGL losing much of it's support from both software and hardware companies.
