Thanks for the clarification, bought the limited but will upgrade to the ultimate to get more friends in it
There is an Ultimate Edition. We will be releasing more information on it as we approach Early Access. You can upgrade your packs in-game as soon as Early Access begins. Purchasing any pack doesn't disqualify you from upgrading to another pack after launch.
As for the footage, there's a fairly involved process (for better or for worse) for capturing footage that we can easily release. That said, we had the game running on X1 and PS4 Pro in our meeting space at E3 and, while you don't have to take my word for it, they both look great.
