Agreed, I can see Skull Kid either way. He's currently one of the most popular predictions due to seeing the Moon as an AT, but no Skull Kid AT and Skull Kid not being a part of the Moon AT. So it's a safe guess for someone without any information who is trying to maintain a reputation.
Similarly, "we're getting a Pokemon" is something that a lot of people believe. It's an ultimate safe guess. And saying "it's not one of these three" isn't that much of a risk, considering that there are some 800 others to choose from. Odds are pretty good that if we're getting a Pokemon, any three randomly chosen Pokemon would not be playable.
They've both waffled on info, acted coy, outright trolled, etcetera. That's not typical behaviour for leakers (or the way either of them behaved when they gave their accurate info).
Their guesses may be accurate, but they're just that. Guesses.
Eh, they forgot to give Bandana Dee a shadow. 7/10
