40-49%: I could go either way, slightly leaning towards less likely.
I don't see why it couldn't happen. Game Freak can do whatever they want. There's nothing stopping them from adding new types.
That said, I don't think it will happen, but also wouldn't be surprised if it did.
There is a reason -reworking the entire, already good as is, blance system. -due to the type(s) being added so late in the series, there most likely will be a severe lack of them or some pokemon might be retconned.

Interesting. As I post this, the poll has the same number of votes as the 2nd one I posted. It seems the whole poll has shifted up a little; in other words, people seem to be thinking it's generally more likely.
Of course there's probably something horribly wrong with how I set this up and you really can't infer anything from it but hey. Still somewhat interesting. --- I summoned a baby to attract a lion. It didn't seem to work, so I tried a delicious baby. Regular baby ATE delicious baby. Horror....horror.~Gameplayingperson
