They do have some info that people are unsure if Capcom still holds canon about. The ancient civilization info from the monster hunter encyclopedia and stuff though they have decided to keep alot if not most info from that book, it is unknown if they are still keeping the ancient civilization story as canon.

Hope MH4 will clear up some stuff because as of yet Capcom has yet to add anything that contradicts, removes or prove the following info regarding Dragon technology and should only be held as mystery. Well it makes a good story base for MH4 if they use it. WARNING use Google translate on the pages. Hope your good with engrish.

Consider it canon or not Capcoms weapon info from some weapons seems to push closer to it being kept as canon.
