Telltale's Back to the Future and Jurassic Park may be digital-only release right now, but the company says that they're going to be heading to retail in a physical format before too long. Telltale's head of publishing James Lamorticelli talked to MCV;

“Telltale’s strategy has always been to take our games to retail in as many markets that we can across the globe. Historically, we have released most of our brands at retail in varied territories and our intent is to continue to reach retail audiences with all of our future releases as well."

I have a feeling this is going to help these games out a lot. People may not be exactly aware of these games in the general martket (you know, the regular people who don't read sites like this and follow every bit of news on games). Seeing a Back to the Future or Jurassic Park game on a store shelf is going to get a lot of impulse buys I think. If the rumored game based on The Walking Dead comes to fruition I imagine it'll receive the same treatment.
