Back... to the shelf! Telltale games has told MCV that they'll be producing "end of season" type releases for their Back to the Future and upcoming Jurassic Park adventure games. Much like their Sam & Max games, a retail disc will be released after the current 'season' ends that contains all the digital episodes- just printed on a little shiny disc and nestled into a colorful cardboard box.
You'll have to wait a while though, BttF is only one episode in so far and JP hasn't even started yet. But there will be something to tide you over- Tales of Monkey Island hits this March.
