I much prefer being the strong silent type. It allows us to give the protagonists their own personalities and let's us imagine what they'd say if we were them. Which technically we are them, and that's something I think GameFreak has always aimed for since the very birth of the games. So I don't think we'll ever see prominent dialogue for them other than the basic "Yes" and "No" options and what happened in B2W2. I hope the latter doesn't happens again and is just something that suited that special occasion; fingers crossed.
