A couple of things the console sub section could have:
-A thread for people to brag about their gear
-A thread for setting up play groups / sharing psn / xbl account names
-A thread for a guide on how to dupe items (if it's allowed?)
-A thread for a guide on how to get infinite guaranteed legendary drops from Diablo inferno (if it's allowed?)
And of course, the regular threads for questions, ideas and whatnot.
I think it can be pretty nice to have this sub section even though it will most likely not be the most active section on this forum, but still probably more active than the "other games" section... or the roleplay section, etc...
