It really bugs me that despite the Generation I Starters being the first Pokemon to introduce the Type Triangle, it's complicated right off the bat with Grass/Poison---I've always thought that dual-types weren't introduced too gracefully in Gen I, most of the ones you run into you won't realize they're even dual-types or how it applies without looking it up. The majority of Flying-type Pokemon you meet are part-Normal, and thus neutral to Fighting, for example as are the majority of Rock-types part Ground leading many to believe for the longest time they were immune to Electric.
But Poison and Flying don't effect Water or Fire, I don't think we'll see a Starter being with a type that would mess up the Triangle---so Water/Ground would be out since it'd have 4X to Grass.
Likewise we'll probably never see a Ghost, Steel, or Rock off the bat because they'd have an advantage over the majority of early game Pokemon due to being immune or resistant to Normal-type attacks.
