I can't bring myself to read the responses in this topic, so I'll just say that the article in the OP is purely speculation.
Kojima already confirmed during the Konami E3 Press Conference that this would still be a stealth game, just different from what we're used to (which might mean more action oriented, but stealth nonetheless), and that alone invalidates this entire topic.
