Yes, things are happening, we're just slow.
First all of Telltale's [iPad damn it] games are now $2.99 until February 10th. Of course, no new episodes have been released yet, and chances are slim they will be if history is anything to go buy. (The Penal Zone has been out for closing in on a year now.)
Also, if you haven't subscribed to their newsletter, you probably should, as the newest edition has some new Back to the Future images. Which is awesome. They're also offering the full season of Sam & Max: Beyond Time and Space for $4.99 to newsletter subscribers.
So yes. Do it. And stuff.

Just wanted to point out you wrote "all of Telltale's game" instead of all their iPad games.
Ah, thanks!
To comment on the actual post, I will probably pick up the ones that are finished or are confirmed they will later be finished on the iPad (Puzzle Agent & Tales of Monkey Island). I posted a thread asking about whether Wallace & Gromit would be finished for the iPad in the Telltale Games forums. Hopefully I get a response. If there's plans to finish that series, I'll pick up Last Resort too.
