I was at a wedding and saw two of my nephews there. These guys are in their low 20s, got jobs, have the internet, but aren't like us. They don't hang out on the web trying to sponge up rumors on 4e. They just go by what they passively receive. They are, however, really into D&D. Like to talk about it with me when they see me. I mentioned 4e to them and asked if they were excited. They're response:
"I heard it was going to be all on-line."
I was curious about that response, so I started bringing up 4e with some of my other D&D acquaintances (people I know play D&D, but aren't friends or family), and I'm getting about the same: that D&D4e will require internet access.
I'm wondering just how much the non-geeked-out crowd is really getting to know about 4e. By time 4e gets released, there may be a lot of damage that needs to be undone.
