Some cards from Commander 2017 leaked, so we know what one of the tribes is now.

Relevant new type: Cat Dragon

@JonTheMon Theory: mouseover for spoiler

EDH idea: Cat deck where each cat must be a "Cat ____"

Hmm, there are a lot of cat warriors and cat clerics, though....

Most Cats have another type

Yeah. I suppose I was thinking more Cat Monkeys or Cat Snakes or Cat Dragons.

Well, depending on which other types you're looking for, I count about 25 creatures like that.

Hmm, that's not a lot.

I just discovered something a little weird: there are 6 whales in Magic. 3 of them have or can gain flying

Only two are from Kaladesh block

I changed my mind on that theory. It's more likely spoiler because spoiler

I like the idea of them including creatures in one commander deck which could feasibly fit right into another commander deck, though

They don't really do splashes in the preconstructed commander decks

they haven't done a tribe before though, they've focused on colors

And so far, the leaked cards have completely balanced colors
