The way I see it, this could go one of two ways.

If the guys have come up with a twist for this game then the three logical guess's I can make are as follows:

- Dr. Gordon will be involved (Sorry to Some)
- Tapp Will Die
- Tapp will Live and be woven into Saw VI. Therefore the twist is that we find out he is somehow connected to VI.

But he will probably die. If any Saw spinoff can make the return of Gordon feel realistic however it would probably be in the Game.
