I actually saw another site claiming a November 21st release date was rumored just a few days ago. So, I think this maybe legit.
Well, I would say that the release date maybe a shot at taking the wind out of Microsoft's sails, I don't think they are being as reactionary as some people think. I'm pretty sure there was never DRM or online requirements in the PS4, though they may have considered them. Which would explain why Microsoft is using them. I think this was just good planning on their part, though.
Also, it suddenly struck me how odd it is that two of the biggest console makers are an electronics company and a software company. Considering that Nintendo and Sega were once the top dogs. Nintendo still exists, but is seeming more niche these days.
