I don't think they will "come back". But then again, I don't think they ever left. They are just now a niche market and not seen as widely as the standard size. And I believe that is where they will stay.

I would not mind if they became more prevalent, but I think it is an issue of paint availability (as stated by others). Paint size issues for paintball is similar to ammo size in the Armed Forces. It has been a determining factor for weapons changes over the years.
