I want to chime in to revise my above statement. I've pretty much abandoned all notion of walker caps and now have almost 65 walkers in my 540 cube. I've found that having more walkers helps midrange decks fight against control strategies and that "superfriends" decks fold to well built aggro decks easily.
I don't keep a hard cap but it's definitely something I think about. This set isn't going to break the planewalker balance wide open though, we might get 3-4 if we are lucky.
In my 540 I'm generally sticking to:
5 per color (and eventually colorless)
1ish per guild (Izzet breaks this but some guilds don't have a walker I like yet).
Once all of that criteria is filled I'd have about 40 walkers in a 540 cube. This comes down to a tad more than 1 walker per pack on average which feels good to me. I agree w/ BZ Gunshot. It's not about the walkers its about the gameplay. I think gameplay is going to get better and more interesting the more unique and archetype supporting walkers we get.
