Well the problem is that there are so many devices out there to support. The chat session showed the company is very responsive to user demand, so if enough people request ELK support, then I don't think it would be a problem.
That said, it's a linux based platform, and the ELK protocol is very easy to implement, I don't see why someone wouldn't write a driver if Securifi ends up putting it on the back burner (heck, I might do it myself). I don't think it's fair to compare the router to the Pebble, but if you are really concerned, read the transcript, it put my mind at ease.
Out of curiousity, how did you miss the chat announcement? I tried to post a notice everywhere, but looks like I might have missed something.
