Well, as I said before, there's only two reasons that Sakurai wouldn't directly deconfirm Ridley as he's done with tons of other characters: the character/hazard isn't ready to be shown, or he's being a troll. Having Ridley unfinished in the Direct isn't a huge deal, 'cause they'd have likely had him done by now in either case. What we were shown there was more than likely a mix of both: whatever Ridley's status, playable or hazard, it was unfinished but in a state they could feasibly use it to troll us. 'cause, honestly, I don't FEEL like it's a deconfirmation, but the evidence we have right now isn't what I really consider conclusive and, in fact, feels more indicative of a non-playable Ridley.
Anyway, I know the evidence we have has convinced a lot of people here, and I don't mean to undermine the great lengths people have gone to try to prove there's more to it than is being presented to us, but I prefer to hope for the best but expect the worst, and developers like to keep things simple. Sometimes, if it looks like a dog, it barks like a dog and the sign says it's a dog, then it's a dog, y'know? A big ol' trollface dog that sounds like Sakurai, but still a dog nonetheless.
