Yesterday, IGN posted a quick skim-through of an interview they did with Telltale Games CTO and co-founder Kevin Bruner, in which he clarified something about the upcoming Back to the Future and Jurassic Park games: they are pilot episodes. This means that the possibility of more episodes being made is directly proportional to how much money you give Telltale interested you are in either series.
(BREAKING NEWS UPDATE: Proving the wisdom of Kroms' aspersions cast on Levi Buchanan's journalistic skills, Telltale designer Sean Vanaman has informed us (and the world) via Twitter that Jurassic Park and Back to the Future will NOT be part of Telltale's Pilot Program, but instead full-length Sam and Max-style episodic seasons.
We now return you to your regularly scheduled news post...)
Interestingly, the preview mentions that "[Telltale] recognize that shoehorning [the games] into an established point-and-clicker was the wrong way to go – but that's also one reason they wanted at them." This sentence could mean one of three things: that Telltale tried and failed at making the games traditional point-n-clickers, and are thus switching genres (possible); that Telltale tried working Jurassic Park or Back to the Future into something already "established" like Sam and Max (wishful); or that IGN scribe Levi Buchanan's grammar is worse than a Babelfish translation of Romance of the Three Kingdoms (probable), and what he means to say is that Telltale decided to pick-up the franchises because they were likely to not work as point-n-clickers/draggers, and would thus open-up new gameplay channels for Telltale.

However, I'm concerned that this narrows Nelson Tethers' odds of finding himself in a full series.
