Why has Nvidia not replied or given any statement about Mantle?

This was posted in the console subforum before anyone had heard about Mantle. I can't see the link while at work, but some of the quoted parts seem to be downplaying the 'to the metal' advantages over DX. Now, this is telling now, because before it was like NV were sort of saying they don't care about console performance; but, this happened just before the Mantle marketing slides that seem to have a bunch of non developers all hot in their pants of some imagined 50% performance increase.

Nvidia already responded to Mantle, you guys just missed it. They were subtle enough it didn't even register for most people.

I saw that but don't see a direct correlation. Maybe i took it wrong but I see it as a "we don't care about consoles" response.

From that Article -

"Things have changed, though. Direct X has gotten much, much better compared to where it used to be. The barrier between Direct X level of interface and to-the-metal interface has gotten much closer. It used to be huge, but not so much anymore. Also, I think the PCs and the consoles look alike these days. The PS4 and Xbox One have an x86 CPU, a PC-style GPU. It’s a giant integrated graphics PC"

Indeed, that is a to-the-metal reference and may offer a gauge or insight on their thought process here, thanks!
