Hey guys, this is Chris, the writer of that amazing article. Besides some enhanced textures and native widescreen support, I can't find anything specific as far as gameplay enhancements go. I think I prefer that though as it still stands up today.
That being said, I reached out to SkyBox and they directed me to Microsoft for press inquiries. They also wouldn't answer my follow up on a hard release date, though they really wanted to. Unfortunately, they wanted to keep their job more.
I'll update if I get more info soon.
