Well, as I have said, I think Epic want to make a Jazz game. The question is, when and how. It's a question of when because they need to time it right so that it gets a lot of attention, and it's a question of how because there aren't a lot of people who'd buy a new Jazz game as things are. If Epic are smart about this, which they obviously are, I think they'll re-release(Or HD Remake) Jazz 1(CD) and 2(TSF), this way, new fans can be brought in, and old fans who remember it from childhood can easily revisit it, and perhaps join in the Jazz community. Then a new Jazz game would have the best chance of doing well. And, if they do re-release Jazz 1 or 2, or both around the 20th anniversary of the first game, they could have some kind of special 20th anniversary deal(Some kind of sale, perhaps?). Who knows, it could sell well and make a Jazz sequel a justified priority.

Also, I'm pretty sure Epic are aware of all the fan patches and all that that the Jazz series has. If I remember correctly, they have linked to J2O quite frequently in the past, so they are aware of us, and I doubt they would be able to ignore Plus's existence.

(Also, I don't count the Jazz Twin-Stick Unreal Demo as a Jazz revival attempt, I think of it as Cliff Bleszinski trolling us)

Wow, that's a lot of speculation(Although, to be fair, it is fun to speculate about the future). XD
