That's not exactly an "oh by the way" kind of thing. That's actually a rather big thing. Just look at the situation with Bombshell. Even after speaking with Fred about it, I still don't fully understand what went on with that, and I wager I probably never will.
See the only thing that concerns me is that i've heard somewhere that the rights to do any kind of remakes or HD enhancements to these games is a no-no. Well, see, that's a potentially kind of a vague thing to have floating around there if it's true. It could very easily stop them from doing ports to the PC. It depends on what the actual agreed upon language is.
We can't know, we won't know, and I suggest to any new comers, even though this is a new and improved 3D Realms, just trust some of us old dogs, it's best you not go off on a sugar rush of excited glee at "new" or "revisited" Duke Nukem content until a press release makes it to the front page and remains unmolested by the army of game company lawyers.
