Interesting. The other thread got me thinking, so I asked Adam on twitter if they're counting shadow jago as a season 2 or season 3 character. Apparently they count him as a season 1 character.
This makes me wonder.
Season 1 gave us 7 returning characters, 1 new, 1 bonus.
Season 2 gave us 4 returning, 4 new, 1 bonus.
Season 3 can potentially give us 4 returning again, if Eyedol comes back. 4 new, plus Rash as the bonus character would follow Season 2's pattern.
But if we are truly getting more than one guest character, then that means we are either getting less original characters, or more than 9 characters this season. (I guess you could argue that even guest characters are "new" characters in a way, but that's not the same as completely original characters like we got last season.)
