The leaker was wrong about psychic resisting fairy so some info could just be red herrings.
If the leaker is wrong about the starter types (I think he tells the truth for the record) then I predict these as the starter type combos:
Chespin:
Grass/ Ground: please no, I like when starters have unique types which is why I haven't chosen fire since gen 3. But it makes sense and it knowing mud shot points it even closer in that direction.
Grass/ Rock: very cool type combo offensively and defensively, there's not a whole lot pointing to it (roll out isn't good proof, many non-rock types learn it naturally)
Pure Grass: grass by itself isn't good especially on something slow.
Fennekin:
Fire/ Fairy: very nice offensive coverage, the design looks very magical and what better way to introduce a new type to the public than a starter? (I'm aware of johto)
Fire/ Dark: meh, it makes sense but I'd prefer something better. Teruuna's design does have a sly look to it, but maybe I just keep seeing zorua.
Froakie:
Water/ Dark: It really looks like he's heading in that direction, his color scheme and body language really say Dark-type to me.
Water/ Flying: Mainly wishful thinking, his agile and nimble appearance keeps saying flying type but so did grovyle...
