Yep, no harm in talking about leaks. And if nothing else, it's fun seeing what someone, somewhere, thinks would be a fun or interesting concept in Smash.I agree with this. Speculating on leaks - even ridiculous ones - is part of the pre-Smash hype, and is something we won't get to do again for many years after this. Those who find leak speculation disagreeable are more than welcome to ignore it, but I don't think we should have to avoid it at all. It's harmless fun.
I think a lot of people who have that "speculation on dumb leaks is dumb" attitude are going to find that they miss all the discussions and theorizing about the games' characters, stages and features once both of them are actually out and the surprise is gone.
