The original community manager who posted about Dark Souls needing public support to make it to PC has posted again, saying:

I honestly wasn’t expecting such a massive support. My boss(es) even came to talk to me about this, after it explodes all around the world. If you wanted to have the attention of Namco Bandai Games, now you have it. The future is in your hands, and I hope you will keep supporting this. I make a personal objective to make sure every relevant people in Namco Bandai Games is in touch with this formidable effort. Great Thanks!

Our PR contact at Namco reports that they are hoping to get an official comment soon. The petition is at almost 72k signatures at the time of writing.
